| Abstract: | Sodium diethyldithiocarbamate (DDTC) can react with copper to form a complex, Cu(DDTC)2 in the presence of Triton X\|100,which has the function of solubilization and sensitivity,thus obtaining a method of determining trace copper by DDTC\|TX\|100 micelle solubilization direct photometry.This method features easy and quick operation,good selectivity and better accuracy.The relative standard deviation,recovery rate and Mole absorptivity are 0.843%,96106% and =6.410\+3L/molcm,respectively. |
