Cd~(+) -dithzone-peregal o system spectrophotometry was studied in this paper. Instead of organic solvent abstract procedure applied earlier, peregal O whichcould be used directly in water system was used to improve solubility for mea-suring heavy metals.

本文对Cd~(+)-双硫腙-Peregal O体系光度法进行实验研究,该法避免了以往双硫腙测定重金属所采用的有机试剂萃取分离法,而用非离子表面活性剂Peregal O增溶,使测定在水相中直接进行。
