| 摘 要： | 经过对锰的氧化物和氢氧化物在净化污染水体中的应用综合研究，发现该氧化物和氢氧化物样品能有效去除污染水体中的有毒有害金属离子和 氧化降解苯酚、2－丙醇、苯及印染废水等有机物，其污染净化能力主要是基于表面络合反应、表面离子交换作用和变价元素的氧化还原作用。同时介绍了锰氧化物和氢氧化物所具有的4个环境属性；离子交换、氧化还原、粒径效应和孔道效应，提出将结构特征与环境化学有机结合，深入探讨其环境属性与污染净化能力之间的关系是目前主要的研究方向。

| Abstract: | This paper reviewed the application of manganese oxide and hydroxide to the purification of polluted water system.These compounds are effective to remove heavy metal ions or decompose organic compounds,such as chromium, lead, cadmium, mercury, copper, zinc, cobalt, nickel, phenol and 2 propanol etc.Its mechanism is based on the redox of variable charge element, ion exchange and complex reaction of surface.Manganese oxide and hydroxide have four environmental properties: ion exchange, redox, fine grain and tunneling effect.It is important to combine the crystal structure of manganese minerals with environmental chemistry in harnessing the environmental pollution.The relation between the four environmental properting and the abilities of purifing the pollution is discussed. |
