在硝酸银、氧化银的生产车间和一般化学实验室里工作的人们,难免在衣服和皮肤上沾染银盐溶液,二、三小时后被沾染处出现了黑色银迹。1934年Б.В.Некрасов曾提出可用浓的碘化钾溶液处理,然后用水洗。我们经过试验,此法并不能完全清除银迹。寻找清洗效果好、药品价廉,取用方便、无腐蚀和毒性的银迹清洗剂是有实际意义的。本文将通过多种银迹清洗剂清洗效果的比较,找出效果较好、便于使用的清洗剂,
People working in silver nitrate, silver oxide production plants and general chemistry labs are inevitably contaminated with silver salts on their clothes and skin, and black silver marks appear in two or three hours after they are contaminated. In 1934, Б.В.Некрасов proposed to be treated with concentrated potassium iodide solution and then washed with water. We have been tested, this method does not completely clear the silver. Looking for cleaning effect, cheap drugs, access to convenient, non-corrosive and toxic silver cleaning agent is of practical significance. This article will be through a variety of silver cleaning agent cleaning effect comparison to find out better, easy to use cleaning agent,
