Abstract:
An express quantitative test is recommended for determination of hydrogen sulfide in waste waters, based on linear colorimetric principle, which could be used for concentration scopes: 20-400 mg/l with sensitivity 10 mg/l; 10-250 mg/l with sensitivity 5 mg/l. The reproduction of the test is very good--the coefficient of variation do not surpass +/- 10%.
