The anodic behavior of electrolytic nickel anode in nickel sulfamate plating Solution was investigated,using anodic polarization curves,metallographic observation of cross-sections of nickel deposits,Hull Cell tests with solutions with and without Cl-,F-,bending tests with five solutions of different compositions,and sulfur content analysis in nickel deposit with mass spectrometry.

采用极化曲线、金相观察、赫尔槽电镀试验、弯曲试验和质谱分析方法，研究了氨基磺酸盐镀镍的阳极行为，证明了当在氨基磺酸盐镀液中使用电解镍阳极时，其活化峰值电流和镀液组成有很大的相关性，当镀液中不含F-和Cl-时其阳极活化峰值电流小，阳极处于极化状态，或相当大面积处于极化状态，使氨基磺酸根在极化的阳极表面氧化，从而使含硫化合物夹附于镀镍层，形成镀层内应力，并使镀层成为层状结构，并出现半光亮的外观。

The present invention adopts ammonium salt solution as leach, and adopts the liquid-phase oxidation activating agent formed from surfactant sodium ligno-sulfonate or sodium dodecyl sulfonate, liquir phase oxidation catalyst Cu(2+) and sulfur-extracting agent tetrachloroethylene to implement quick leaching process of sulkfide mineral in gas-liquid-solid three-phase reactor, all the sulfurs contained sulfide in mineral powder can be converted into elementary sulfur and sulfuric acid radical, the contained zinc, copper, nickel, cobalt, lead, cadmium and silver can be changed into soluble salt, and fed into leach or remained in the leaching out slag.

本发明涉及的有色金属硫化矿的铵盐液相氧化直接浸出方法，其特征在于：采用铵盐溶液作浸出剂，采用由表面活化剂木质磺酸钠或十二烷基磺酸钠，液相氧化催化剂Cu2+、萃硫剂四氯乙烯组成的液相氧化活化剂，在气液固三相反应器内，实现硫化矿的快速浸出过程，矿粉中各种硫化物所含的硫转变为单质硫和硫酸根，所含的锌、铜、镍、钴、铅、镉、银等变成可溶性盐类进入浸出液中或留在浸出渣中，消除传统流程中二氧化硫，硫化氢，氮氧化物及含砷含汞含铅等有毒烟气的排放。

Medium added inhibitor, could slow down the corrosion of equipment and valves, such as chrome-nickel stainless steel in sulfuric acid containing no oxygen, the great state of cremation within the range of solubility, corrosion more serious, but a small amount of copper sulfate or nitric acid and other oxidants, can change the passive stainless steel surface generates a layer of protective film to prevent the medium of etching, in hydrochloric acid, if a small amount of oxidant, which reduces the corrosion of titanium.

介质中添加缓蚀剂，可使设备和阀门的腐蚀减缓，如铬镍不锈钢在不含氧的硫酸中，很大的溶度范围内成火化态，腐蚀较严重，但加入少量硫酸铜或硝酸等氧化剂，可使不锈钢转变钝态，表面生成一层保护膜，阻止介质的的浸蚀，在盐酸中，如果加入少量氧化剂，可降低对钛的腐蚀。
