摘要
用氢氧化铝和氢氧化锂制备铝盐吸附剂，研究了其对锂的吸附性能。结果表明，在Al（OH）3/Li（OH）摩尔比为2．0，酸洗时间3～4h．酸洗pH为5．8的条件下制备出的铝盐吸附剂，对锂离子的吸附性能稳定，吸附量可达到0．6～0．9mg．g^-1，而且对卤水中锂的选择性较高，对Mg^2＋，Na^＋，K^＋等金属离子基本不吸附。
The preparation of aluminum salt adsorbent using Al （OH）3 and LiOH was described. Then the display of lithium adsorption capacity out of salt-lake bittern was concerned. The experimental results confinned that the optimal synthesis conditions were 2.0 of the Al（OH）3/Li（OH） molar ratio, 3 - 4 h of the acid-treating time and 5.8 of the acid-treating pH adjustment. The aluminum salt adsorbent prepared under those conditions showed high adsorption stability and the uptake of Li ^＋ ions from salt-lake bittern could usually reach 0.6- 0.9 mg·g^-1. Great selectivity of Li^＋ ions rather than other alkali or alkaline-earth metal ions was found in the multi-ions simulative bittern experiments.
