| Abstract: | In this test,a kind of emulsion op is as the mediate of the develop reaetion of Cu?-PAN and the conditions of this reaction are studide.As a result,the last absorption wave length of this system is 555?nm,the rang of acidity is from pH 7.0 to 10.3.the quantity of copper from 0 to 50?μg/50?mL.is agreed to the lamber-Bear′s law.The molmar absorption is 4.23×10 4?L·mol -1 ·cm -1 ,In this test,the interfrence ions and the methods of deleting them are studied. |
