COLORIMETRIC DETERMINATION OF ANIONIC SURFACE ACTIVE AGENTS IN COASTAL, RIVER AND LAKE WATER
水域中阴离子型表面活性剂的比色测定

Conditions for colorimetric determination of anionic surface active agents that could lead to the reduction of extraction agent and simplification of analytic procedure, various interference ions and determination error are given in this paper. The minimum concentration -determined is 0.1 ppm.
