研究多种因素对水合五氧化二锑(HAP)及水合五氧化二锑-磷磷钼酸铵(HAP-AMP)制备的影响,在实验条件下找到了HAP及HAP-AMP的最佳制备工艺。分别考察了HAP对Sr~(2+),HAP-AMP对Sr~(2+)、Cs~+的吸附性能。结果表明:在实验条件下,HAP对Sr~(2+)的最大吸附量可达0.73 mmol/g,而HAP-AMP对Sr~(2+)、Cs~+的最大吸附量可分别达到0.47 mmol/g和0.32 mmol/g;同时,HAP-AMP对Sr~(2+)、Cs~+的吸附还有显著的选择性。
The effects of various factors on the preparation of hydrated antimony pentoxide (HAP) and hydrated antimony pentoxide-phosphomolybdate ammonium molybdate (HAP-AMP) were investigated. The optimum preparation conditions of HAP and HAP-AMP were found under the experimental conditions . The adsorption properties of Sr ~ (2 +) and Cs ~ + by HAP on Sr ~ (2 +) and HAP-AMP were investigated respectively. The results show that the maximum adsorption capacity of HAP to Sr 2+ can reach 0.73 mmol / g under the experimental conditions, while the maximum adsorption capacity of HAP-AMP to Sr 2+ and Cs + can reach 0.47 mmol / g and 0.32 mmol / g, respectively. At the same time, the adsorption of HAP-AMP on Sr ~ (2 +) and Cs ~ + was also remarkably selective.
