Abstract
A simplified procedure using diffusion and a sulfide ion selective ele ctrode is described for measuring acid-volatile sulfides (AVS) in sedi ment. This method yielded at least 100% more AVS than the more common purge-and-trap method. The quantity of AVS (based on dry mass of sedim ent) was found to be dependent on acid concentration and on mass of we t sediment. The mean recovery of known additions of sodium sulfide was 93.8 +/- 6.70%
