如醋酸、氨水、氟離子、乙二胺四乙酸、有機磷酸鹽等。鎳離子一旦與這些絡合劑絡合之后，十分穩(wěn)定，無法通過絮凝沉淀或者離子交換的方法將其去除，因此呈溶解性的絡合態(tài)銀極易引起廢水超標。[0010]中國**CN公開了一種采用酸化法破絡合技術對電鍍鎳廢水進行前處理，在強酸條件下，常用的絡合如檸檬酸、氨水、草酸等失去或減弱與鎳離子絡合能力，從而可使絡合態(tài)的金屬鎳游離出來，該方法能使部分較弱的絡合劑釋放出鎳離子，但是該方法存在的不足是:其無法釋放有機磷酸鹽類絡合劑如乙二胺四甲叉磷酸鈉所絡合的鎳。此外加酸之后，在后續(xù)的樹脂吸咐鎳離子的工藝環(huán)節(jié)會降低該樹脂對鎳的吸附容量及性能。[0011]中國**CN提出采用芬頓氧化技術使鎳的絡合物破除形成自由鎳的方法。該方法依據由芬頓氧化產的羥基自由基與二價鐵離子具有一定的氧化還原能力，對絡合物進行降解，從而破除絡合形態(tài)的鎳形成游離態(tài)鎳。芬頓氧化雖能有效地氧化降解水體中有機污染物，然而對Ni-EDTA絡合的降解釋放效率較低。因此，該方法只能破除絡合能力較弱的那部分鎳的絡合物，對于絡合能力較強的鎳絡合物破除效果不明顯，無法達到持續(xù)穩(wěn)定的除鎳效果，同樣，該方法也易導致鎳排放超標。</p><div

分析其原因可能是碘的化合物與染料反應形成具有保護作用的碘化物，碘化物與鋁發(fā)生反應，形成耐水的沉淀物，保證封孔質量；2）在封孔劑中加入鉬酸鹽以及鑭的化合物，能夠生成鉬的氫氧化物及鑭的氫氧化物，生成的氫氧化物能夠將陽極氧化膜的孔隙封閉且在封孔過程中能夠吸附到孔隙中提高鋁合金的抗腐蝕性能；3）在封孔劑中加入磷酸鹽及硅烷偶聯(lián)劑能夠吸附到陽極氧化膜孔隙中，并將其填充封閉，從而減少染料在封孔過程中掉色，提高鋁合金產品的抗鹽霧性能；本發(fā)明通過鉬酸鹽、磷酸鹽、碘的化合物、鑭的化合物和硅烷偶聯(lián)劑的配合使用，能夠有效地防止或減少鋁合金陽極氧化膜染色處理后的染料掉色，并提高鋁合金陽極氧化膜的封孔質量及產品的耐腐蝕性能。推薦地，所述鉬酸鹽為鉬酸鈉和/或鉬酸銨；所述磷酸鹽為磷酸鈉、磷酸鉀或三聚磷酸鈉中的至少一種；所述碘的化合物為碘化鉀、碘化鈉和碘化銨中的至少一種；所述鑭的化合物為氯化鑭和/或氧化鑭；所述硅烷偶聯(lián)劑為γ-(2,3-環(huán)氧丙氧)丙基三甲氧基硅烷、γ-氨丙基三乙氧基硅烷、苯胺甲基三甲氧基硅烷和脲丙基三乙氧基硅烷中的至少一種。推薦地，所述封孔劑還包括苯磺酸鹽。</p><div
