Acidity

The 7604-DR uses a standard alkali to titrate to the methyl orange endpoint for determination of strong mineral acids, and the phenolphthalein endpoint for determination of strong mineral acids, carbon dioxide, other weak acids and hydrolyzable mineral salts. The results are expressed as CaCO3.
The 7182 uses the phenolphthalein endpoint to determine hydrochloric, sulfuric, and phosphoric acids.

Ammonia Nitrogen

Ammonia Nitrogen: Two colorimetric methods are available. Nessler's reagent reacts with ammonia to form a yellow to brown color; salicylate reacts to form a blue color, which in combination with the yellow reagent color, produces colors from yellow to blue. The salicylate method is preferred for salt water analysis and does not contain mercury salts as does the Nessler method.

Arsenic
This procedure requires about 15 minutes and employs a test strip. Inorganic As+3 and As+5 are converted to arsine gas. This reacts with the test strip in a closed container and produces yellow to brown colors on the strip. The strip colors are compared to a color chart to determine the concentration in ppb.

Bleach

Free, combined, and total chlorine may be determined using DPD with either colorimetric or titrimetric methods. These determinations are generally limited to concentrations of 0-10 ppm, although the FAS titration can test higher concentrations with the addition of more DPD indicator. Higher concentrations require the iodometric titration, whereby the sample is acidified and iodide is added, which is oxidized by chlorine to iodine and is titrated with a standard thiosulfate solution.

All results are as CaCO3; some kits also express results as gpg. The 3609, which is recommended for salt water analysis, includes a conversion factor for Ca++. The -LI suffix indicates an all liquid kit; -LT indicates a liquid buffer and tablet indicator.

Color

The color of water is usually compared to platinum cobalt color standards representing APHA Standard Color Units. A second visual test involves the use of 2 tubes, one filled with the sample water, the other with color-free water. A standard color solution is added to the second tube dropwise until the color in the 2 tubes matches. The number of drops of color solution is multiplied by a factor to give the result in APHA color units.

Nitrite, Sodium

Sodium nitrite is titrated using one of two methods. After acidifying the sample, permanganate will oxidize nitrite. When all of the nitrite is oxidized, the permanganate turns the sample pink. Ceric Ammonium Nitrate (CAN) also oxidizes the nitrite in the presence of ferroin indicator. The endpoint is orange to blue. The CAN method is preferred if glycol is present.

Oxygen, Dissolved

The azide modification of the Winkler method is a modified iodometric titration whereby oxygen, in the presence of a strong alkali, oxidizes manganese, which in turn reacts with iodide to form iodine. This is titrated with a standard thiosulfate solution in the presence of a starch indicator to enhance the endpoint. Azide eliminates nitrite interference.

pH

pH must be controlled and monitored because it plays an essential role in almost all chemical and biological processes.

LaMotte pH Test Kits

Each test kit consists of an Octet Comparator, graduated test tubes, and a bottle of indicator solution for 50 tests. LaMotte Company has been supplying laboratory quality pH indicator tests to professional analysts for more than eighty years; these are the most reliable, economical pH test kits available. Simply fill the tube to the mark with the sample water, add several drops of indicator, and compare the resulting color against the eight permanent color standards in the comparator.

How to Select the Right pH Kit:
Single or Wide Range?

Single range kits cover a range of 1.4 pH units in 0.2 unit increments (0.1 unit sensitivity). Wide range kits may cover as many as 7 pH units in increments of 0.5 or 1.0 pH units (0.25 or 0.5 unit sensitivity).

Which Range?

Choose a kit in which the midpoint of the range covered is as close to the average or optimum pH value of the sample water. If this value is unknown, choose a wide range kit.

Indicators specific to a particular pH range allow colorimetric determination of pH. If the water to be tested is cloudy, one may wish to employ the bicolor reader.

Phosphate (Total): Polyphosphates (acid-hydrolyzable or condensed) and phosphonates (organic phosphates) are reverted using the reagents and apparatus in the 7884 Auxiliary Phosphate kit. The polyphosphates require boiling or microwaving with acid and subsequent neutralization; the phosphonates require the same, but with the addition of an oxidizer in the boiling/microwaving step. Once reverted to orthophosphate, any of the tests in the orthophosphate section above may be used for analysis.

The chromazurol S method may be used for Dequest, Bayhibit, Belcor 575 and Belsphere 161 phosphonates. The indicator changes from yellow to pink at the pH ideal for the reaction, then thorium nitrate is added until the solution turns purple.
The Xylenol Orange method titrates all Dequest products and Belcor 575. The pH is adjusted to 2.5-3.0, then thorium nitrate is added until the color changes from yellow to red.

A colorimetric method is available for waters where metal interference is unlikely. An excess of iron is added to the solution containing polyphosphate. The iron is complexed and the remaining iron is determined. The polyphosphate concentration is derived from the iron concentration.

QAC

Two methods are available. A masked bromphenol blue indicator is added to the sample and turns green. Sodium tetraphenylboron is added to complex the QAC and the color changes to red. This method is best suited to higher QAC concentrations. A polyelectrolytic titration like the one used for polyquat, is used for low to high concentrations.

Sodium Nitrite

Sodium nitrite is titrated using one of two methods. After acidifying the sample, permanganate will oxidize nitrite. When all of the nitrite is oxidized, the permanganate turns the sample pink. Ceric Ammonium Nitrate (CAN) also oxidizes the nitrite in the presence of ferroin indicator. The endpoint is orange to blue. The CAN method is preferred if glycol is present.

Sulfide

Both kits use the Pomeroy methylene blue method for analysis. The colorimetric method uses color standards to read total sulfide. Total, dissolved and hydrogen sulfide can be separated in the titration test. The total sulfide is determined using a color dye which is added to an unreacted sample until it matches a reacted sample. The same procedure is used for dissolved sulfide, after insoluble matter is removed by aluminum floc. Hydrogen sulfide is determined by measuring pH and multiplying the dissolved sulfide concentration by a pH correction factor.

Sulfite

An iodide-iodate titrant oxidizes sulfite to sulfate under acid conditions, until all of the sulfite is reacted. The titrant then reacts with starch to form a blue color signifying the endpoint.
