依据最新的欧盟标准 EN 1811：2011《对身体穿孔型组合饰品和其他与皮肤长期直接接触的制品中镍释放的参考测试方法》配制了6种不同浓度的人工汗液，采用电感耦合等离子体质谱仪（ICP －MS）测定了1号18K 金样品在6种人工汗液中溶出的镍质量浓度，利用电化学工作站研究了2号18K 金样品在1倍人工汗液和中性0．5％ NaCl 溶液的电化学行为。其研究结果发现：人工汗液中对镍释放起主要作用的成分是 NaCl 中的 Cl －，其他成分（如乳酸和尿素）对镍释放的作用很小；镍释放量随着人工汗液浓度的增加而增加，主要是由于人工汗液中 Cl －含量的升高。

Artificial sweat with 6 different concentrations was prepared according to the latest version of European Standard EN 1811:2011 (Reference test method for release of nickel from all post assemblies which are inserted into pierced parts of the human body and articles intended to come into direct and prolonged contact with the skin).The nickel concentration of No.1 18 carat gold sample dissolved in these artificial sweat was measured by inductively cou-pled plasma mass spectrometry (ICP -MS).The electrochemical behavior of No.2 18 carat gold sample in one time artificial sweat and neutral 0.5 % NaCl solution was studied using electrochemistry workstation.The results show that the component of Cl - in artificial sweat plays a major role in nickel release,other components such as lactic acid and urea has little effect on the release of nickel;with increasing concentration of artificial sweat,the nickel release rate increases,mainly due to the increase of Cl - content in sweat.
