摘要
利用由河北赤城县金矿尾矿合成的 13X沸石 ,进行了吸附硬水中Ca2 + 、Mg2 + 的实验研究。实验结果表明 ,13X沸石具有较好的硬水软化性能 ,当溶液为中性或弱酸性时 ,Ca2 + 、Mg2 + 的初始浓度分别为 392 4mg·L-1和 10 6 9mg·L-1,按沸石用量 1 0 0 g进行吸附 ,Ca2 + 、Mg2 + 的吸附率可达 98%和 94 %。
The 13X-zeolite is synthesized by the tailing of goldmine in Heibei Chicheng.This paper studied the water-softening propertics of 13X-zeolite.The results show that the adsorption percentage of Ca 2+,Mg 2+is greater than 98% and 94% in the condition of the acidity of solution is neutrality or weak base,mass of zeolite is 1 00g,and the primal concentration of Ca 2+,Mg 2+is 392 4 and 106 9mg/L.The experimental study indicated that the synthetic 13X-zeolite is feasible in softening hard water.
