추출폴라로그래피법을 利用하여 Cu(Ⅱ)를 定量하는 方法에 對하여 검토하였다. 水溶液中 Cu(Ⅱ)를 시트르산암모늄 완충용액(pH=10)에서 DDTC(Diethyl dithiocarbamate) The extraction-polarographic method applied to the determination of micro amount of copper(Ⅱ). Copper(Ⅱ) was extracted into chloroform layer containing diethyldithiocarbamate (DDTC) as Cu(Ⅱ)-D.D.T.C. complex from ammonia-ammonium citrate buffered aquous solution of pH 10 and the alternating current polarogram for the extract was recorded after addition of potassium chloride as supporting electrolyte. This method can be used for determination of the ppb order of copper (Ⅱ) in water with an error of ±10%.
