一、卡巴梅特法铜测定步骤:吸清液1ml于带塞试管:加焦磷酸钠溶液4ml,加茴香蓝2滴,用纯制铵水调节pH到蓝色,此时pH约9,加卡巴梅特溶液1ml,再加4mlCCl_4锰烈摇荡,与标准系比色,如有铜则CCl_4溶液显黄色。二、打萨宗法铜测定步骤:吸清液2ml于带塞试管,加茴香蓝2滴,用柠檬酸铵调节pH至溶液显淡红色,此时PH约为2.8,然后加0.002%打萨宗 First, the Cappadite copper determination steps: supernatant 1ml in a plugged test tube: add pyrophosphate 4ml solution, add 2 drops of fennel blue with pure ammonium water to adjust the pH to blue, then pH about 9, plus Carbamate solution 1ml, plus 4mlCCl_4 Mang strong shake, and the standard colorimetric, if copper CCl_4 solution was yellow. Second, the Sassafras copper determination steps: 2ml supernatant in the plugged test tube, add 2 drops of fennel, with ammonium citrate to adjust the pH to the solution was pale red, then PH is about 2.8, then add 0.002%
