Abstract

Potentiometric and spectrophotometric titration methods were applied to study the relationships in the interaction of polyacrylic acid with copper, cobalt, and nickel ions in aqueous solutions. It was shown that, in aqueous solutions at pH ~ 3, polyacrylic acid does not form complexes with cobalt and nickel ions. A complex is formed with copper ions, but the equilibrium of the complexing reaction is strongly biased towards copper aqua complexes. The sizes of the metal particles were determined using transmission electron microscopy. The metal particles synthesized in the presence of polyacrylic acid exhibited a fairly broad size distribution.

聚丙烯酸与水溶液中铜，钴和镍离子的相互作用

摘要

用电位滴定法和分光光度滴定法研究了聚丙烯酸与水溶液中铜，钴和镍离子相互作用的关系。结果表明，在pH〜3的水溶液中，聚丙烯酸不会与钴和镍离子形成络合物。与铜离子形成络合物，但是络合反应的平衡强烈偏向铜水络合物。使用透射电子显微镜确定金属颗粒的尺寸。在聚丙烯酸存在下合成的金属颗粒表现出相当宽的尺寸分布。
