根据 Cu(DDTC) 2 易浮选于苯中 ,建立了溶剂浮选测定铜的新光度法 ,本法灵敏度高 (ε=2 .9× 10 5L·mol-1·cm-1) ,精密度和选择性好 ,检出限低 ,适于天然水中痕量铜的测定
According to the fact that Cu (DDTC) 2 is easily flotation in benzene, a new photometric method for the determination of copper by solvent flotation was established. The method has high sensitivity (ε = 2.9 × 10 5 L · mol -1 · cm -1) And good selectivity, detection limit is low, suitable for the determination of trace amounts of copper in natural water
