将设计 并合成 的除钼剂 Ｍ１１５ 用于 从工业钨 酸铵溶液 中除钼 等杂质， 取得了良 好的效果 。对含 Ｍｏ ０ ．５６ ～１ ．７５ ｇ／ Ｌ 的 工业（ Ｎ Ｈ４） ２ Ｗ Ｏ４ 解 吸高峰液 ，除钼率 可达９７ ％ ～９９ ％ ，同 时，可除 去 Ａｓ 、 Ｓｎ 等 杂质。将 经 Ｍ１１５ 除杂后的（ Ｎ Ｈ４） ２ Ｗ Ｏ４ 净液进行 蒸发结 晶，当结晶 率为９５５ ％ ～９８７ ％时，所得 产品 Ａ Ｐ Ｔ 全部达 到 Ｇ Ｂ １０１１６ —８ ８ Ａ Ｐ Ｔ—０ 级标 准。同时 ，为结晶 母液中 Ｎ Ｈ４ Ｃｌ 和 Ｗ Ｏ３的回收以 及三废排 放量的 减少找到 了一种 简单高效 的方法。
The designed and synthesized molybdenum removing agent M115 is used to remove molybdenum and other impurities from the industrial ammonium tungstate solution and has achieved good results. Containing Mo 0. 56 ~ 1. 75 g / L industrial (N H4) 2 W O4 desorption peak liquid, in addition to molybdenum rate of 97% to 99%, at the same time, As, Sn and other impurities can be removed. After the M115 impurity-free (N H4) 2 W O4 was evaporated to crystallize, when the crystallization rate was 955% ~ 987%, all the products A P T reached G B 10116 -8 8 A P T-0 standard. At the same time, a simple and efficient method was found for the recovery of N H4 Cl and W O3 in the mother liquor and the reduction of wastes emitted.
