E34 TEST FOR SULFIDES IN WATER

(a) SCOPE. This method describes a procedure for determining the presence of hydrogen sulfide, which is sometimes formed as a result of bacterial action on the sulfates contained in water bottoms in fuel storage tanks.

(b) APPARATUS. 250 ml conical flask.

(c) MATERIALS.

(1) Dilute (10%) chemically pure sulfuric or hydrochloric acid.

(2) Lead acetate paper.

(d) SAMPLES. Representative water samples from storage tank bottoms must be taken in a glass bottle. In some cases it will be necessary to take the water sample in a Bacon bomb sampler. Samples so taken will always be transferred to a glass bottle. To preclude oxidation by air, the filled bottle must be capped immediately. The sample should be tested as soon as possible after sampling to minimize possible changes in the composition of materials in the water.

(e) PROCEDURE.

(1) The sample must be shaken thoroughly just prior to performing the test to make certain that any sediment present is included in the portion of the sample to be tested.

(2) Transfer 100 ml of the shaken sample into a conical flask. Add 20 ml of dilute (10%) chemically pure sulfuric or hydrochloric acid to the flask. Immediately place a piece of lead acetate paper folded in a "V" shape in the neck of the flask. Bring the water to a boil and continue to gently boil for three or four minutes.

(f) REPORT. The presence of sulfides in the sample will be reported if the lead acetate paper shows a black or brown discoloration.
