粉状锈在中性、弱酸性环境中溶解过程的实验研究

为了解氯铜矿、副氯铜矿在潮湿环境中的溶解行为及其特征,模拟中性、弱酸性环境,对氯铜矿和副氯铜矿在此环境下的溶解行为进行监测和研究。通过氯化亚铜的转化制备副氯铜矿。定量地研究了氯化亚铜在水环境中的转化过程。定量研究了氯铜矿、副氯铜矿在中性、酸性环境中的溶解过程。结果表明,中性条件下,氯铜矿比副氯铜矿溶解电离出更多氯离子;弱酸性环境并未导致氯铜矿溶解度增加,但导致了副氯铜矿溶解度的显著增加。

Study on the dissolving process of powdery patina in neutral and in weak acid aquatic solution

In order to find out the dissolving behavior and characteristic of cuprous chloride and paratacamite in humidity environment,their dissolving behavior were studied in simulated neutral and in weak acid aquatic solution.The parata- camite was made through the transformation of cuprous chloride.The transformation process of cuprous chloride in water was researched.The dissolving process of atacamite and paratacamite in neutral and in acid aquatic solution was re- searched.Results showed that in neutral aquatic solution atacamite released more chlorine ions than paratacamite did.In weak acid aquatic solution the solubility of atacamite didn't increased.However,the solubility of paratacamite was im- proved remarkably.
