style="font-family:宋體">該產品專門針對電鍍行業(yè)回收電鍍金液中的金而研究開發(fā)，它主要應用于鍍金液（氰化金和氰化亞金溶液）中金的回收，吸附金明顯，可以看到一層金色的金附著在上面，吸附速度快，吸附量大，可以達到300（質量比）并且后處理方法簡單，回收的金的成色較好。歡迎購買試用</span>黃金吸附樹脂的預處理與復活處理</p><p><span><strong><span>　　</span>一、離子交換樹脂的使用說明</strong></span></p><p>　　樹脂保存方法離子交換樹脂不能露天存放，存放處的溫度為0-40℃，當存放處溫度稍低于0℃時，應向包裝袋內加入澄清的飽和食鹽水、浸泡樹脂。此外，當存放處溫度過高時，不但使樹脂易于脫水，還會加速陰樹脂的降解。一旦樹脂失水，使用時不能直接加水，可用澄清的飽和食鹽水浸泡，然后再逐步加水稀釋，洗去鹽分，貯存期間應使其保持濕潤。</p><p></p><p>離子交換樹脂</p><p><span><strong><span>　　</span>二、離子交換樹脂的預處理</strong></span></p><p>　　將準備裝柱使用的新樹脂，先用熱水(清潔的自來水即可)反復清洗，陽離子交換樹脂可用70-80℃的熱水，陰離子交換樹脂的耐熱性能較差一些，可用50-60℃熱水。開始浸洗時，每隔約15分鐘換水一次，浸洗時要不時攪動，換水4-5次后，可隔約30分鐘換水一次，總共換水7-8次，浸洗至浸洗水不帶褐色，泡沫很少時為止。水洗后，再經酸堿處理，陽離子交換樹脂可按下述步驟處理：</p><p>　　1、用1N鹽酸緩慢流過樹脂，用量約為強酸陽樹脂體積的2-3倍，每小時1.5倍床層體積流過。</p><p>　　2、用水沖洗，出水PH為5左右，用3倍樹脂體積5的NaCl溶液流過樹脂，流速與1相同。</p><p></p><p>離子交換樹脂</p><p>　　3、用1N NaOH流過樹脂，用量及流速與1相同。</p><p>　　4、用水沖洗至出水PH為9左右。</p><p>　　5、用1N鹽酸或硫酸，將樹脂轉成H型，用量為樹脂體積的3-5倍，流速與1相同。</p><p>　　酸流完后，用去離子水沖洗至出水PH值為6以上時，即可投入使用。對于陰離子交換樹脂水洗后的酸、堿處理次序，可采用堿→酸→堿次序，酸、堿用量及流速，強堿樹脂與強酸樹脂相對應，弱堿樹脂與弱酸樹脂相對應。</p><p></p><p>離子交換樹脂</p><p><span><strong><span>　　</span>三、樹脂的復活處理</strong></span></p><p>　　在離子交換樹脂使用過程中，經過一段時間運轉后，往往會發(fā)生出水質量逐漸下降、交換容量逐漸降低等現(xiàn)象。這一般是由于樹脂在運轉過程中受到污染造成。在廢水和生化物質提煉中，由于成份比較復雜，樹脂更易受到污染，因此應采取適當?shù)拇胧┻M行復活處理，針對不同情況，采用不同的復活處理工藝。</p>
