| Abstract: | A new method for determination of copper by spectophotometry with floatation of Cu(DDTC) 2 \|benzene was introduced.It's based on the fact that Cu(DDTC) 2 is easy to dissolve in benzene and can keep stable.This method has high selectivity,accuracy and sensitivity,and the detection limit is low.This method is suitable for the determination of trace copper in natrual water. |
