研究了用功能材料Li_2Mg_2Si_4O_(10)F_2(LHT)、H_2Mn_8O_(16)·1.4H_2O(CRYMO)和Li_(1.3)Ti_(1.7)Al_(0.3)(PO_4)_3(LTAP)分别去除高浓度氯化锂水溶液中的杂质Fe~(3+)、K~+和Na~+.实验结果表明,这几种功能材料分别对溶液中的杂质Fe~(3+)、K~+和Na~+有很高的选择性,除杂效果明显.分析和研究了这几种功能材料在高浓度氯化锂水溶液中分别与Fe~(3+)、K~+和Na~+的交换行为.结果表明,在高浓度氯化锂溶液中这几种功能材料与杂质交换的动力学行为可近似用JMAK方程描述.
The removal of high concentration chlorination by functional materials Li 2 Mg 2 Si 4 O 10 F 2 (LHT), H 2 Mn 8O 16 (-1) 1.4H 2 O (CRYMO) and Li 1.3 Ti 1.7 (0.3) (PO 4) 3 Impurities Fe 3+, K + and Na + in lithium aqueous solution show that these functional materials are effective for Fe 3+, K + and Na + in solution, respectively High selectivity and obvious impurity removal effect.The exchange behavior of these functional materials with Fe 3+, K + and Na + respectively in high concentration lithium chloride aqueous solution was analyzed and studied.The results showed that The kinetic behavior of the exchange of these functional materials with impurities in high concentration lithium chloride solution can be approximated by the JMAK equation.
