Objective At present, the systematic study of heavy metals releasing law from ceramic disc sealed water faucet is lack in domestic. At the same time, nozzle production enterprises also lack relevant knowledge, so it is necessary to study this to provide a scientific basis for the green and sustainable development of the nozzle industry. Methods Through the laboratory simulation method, the inductively coupled plasma mass spectrometer was used to analyze and test the precipitation of heavy metal pollutants in the nozzle, and systematically studied the precipitation law of heavy metal pollutants in the ceramic sheet sealed nozzle. Results Through testing and analysis, the material of the surface nozzle material also determines the precipitation type of heavy metal pollutants. The immersion time and the concentration of inorganic salt in water quality are directly proportional to the precipitation of heavy metals. The lead brass nozzle effectively reduces the precipitation of lead and chromium heavy metals through the lead removal process; the precipitation of lead is reduced by 81% to 86%, and the precipitation of chromium is reduced by 52% to 56%. Conclusion Enterprises can choose suitable materials and processes to produce nozzles according to their own conditions. Consumers should avoid exposure to excessive heavy metals according to their use.

目的 目前国内缺乏陶瓷片密封水嘴的重金属析放规律的系统研究,同时水嘴生产企业也缺乏相关知识,因此有必要对此进行研究,为水嘴产业的绿色可持续发展提供科学依据。方法 本研究通过实验室模拟方法,采用电感耦合等离子体质谱仪对水嘴重金属污染物析出量进行分析试验,系统地研究了陶瓷片密封水嘴中重金属污染物的析出规律。结果 通过测试分析表面水嘴材料的材质也决定重金属污染物析出种类,浸泡时间和水质无机盐浓度与重金属析出量成正比。铅黄铜水嘴通过除铅工艺,有效降低铅、铬重金属析出量;铅析出量降低81%~86%, 铬析出量降低52%~56%。结论 企业可根据自身情况选择合适的材质及工艺生产水嘴。消费者应根据使用情况避免接触到过量重金属。
