铜(Ⅱ)与明胶的络合反应研究——pH值和温度的影响

Study on Complexing Reaction of Copper(Ⅱ) with Gelatin

测定了 p H值为 8.0～ 1 3.0时 ,铜 ( )与明胶的络合比 ,发现随溶液 p H值的增大 ,络合比增加 .

The proportion of chelates of Cu 2+ with gelatin in a pH value range between 8.0 to 13.0 is determined by spectrophotomentry.In a result, the ratio increases with increasing pH value. The proportion of chelates doesn't change almost when the temperature increases.
