中文摘要: 研究了草酸氨沉淀钴过程中NH4 浓度对产品的颗粒和形貌的影响.由于NH4 的作用使溶液的离子强度增加,粒子对体系中阴离子的吸附量增大,粒子的形貌随着溶液中NH4 浓度的增加变粗短,最终形成方形粒子,松装密度增大.
Abstract:The effect of concentration of NH4+ on the particle size and morphology of the product is studied.NH4+ can enhance the ionic strength of solution and the adsorptive capacity of anion.And the particle gets thicker and shorter with the increasing of the NH4+ concentration.Therefore,the particle turn into quadratic form and its loose density increases.
