利江牌D301G树脂产品说明书
一：产品简介：
利江牌D301G是聚苯乙烯骨架的大孔型弱碱性阴离子交换树脂，含有-N（CH3）2，碱性弱于强碱型树脂，容易再生，工作交换量是强碱型的3倍，奈有机污染。采用独特工艺和成，因而具有很高的机械强度和化学稳定性，对氰化物亚金络合物有特殊的选择性，吸附速度快，吸附量大，主要用于黄金提取。
对应国外品牌：Purolite A100，AM-2b
二、产品应用：
吸附过渡元素树脂
三、注意事项：
1．产品的运输与保存：
产品湿态保存，温度在0度以上；长期不用，可密闭或加入5%以上的食盐水；运输时主要是防冻，树脂上面不可防止过重物品，以防树脂被压碎。
2．树脂的预处理：
一般要求可以采用碱-水-酸-水一个流程进行处理，严格要求需作三个循环，***处理成所要求的离子型态。
3．树脂的填装：
要考虑树脂的转型膨胀率大小，预留出足够的空间以防树脂溢出并能***有合适的液面高度；柱径比应在合理的范围，避免偏流；采用湿法装柱或反洗驱除树脂层内的气泡。
4．液体在进树脂柱之前，应经絮凝、过滤或沙滤等步骤，确保不含悬浮物，以免堵塞树脂孔道。
5．柱内长期不用树脂须洗净后掏出保存，或者在抗盐介质内可加盐水，并且需要保持页面不可脱水，同时还需要不定期的反洗树脂，目的是松动树脂，以防结块报废。
