目前很多医院制剂室都采用重铬酸钾硫酸清洁液(简称洗液)处理输液瓶,重铬酸钾系含六价铬离子Cr~(+6)的强氧化剂,与输液瓶中污物作用时,大都还原成三价铬离子(Cr~(+3)),但残留的洗液中还有未作用完的Cr~(+6)存在,极易被瓶壁吸附,比其它异物难以洗去。据报道铬的化合物对人体危害 At present, many hospital preparation rooms use potassium dichromate sulfuric acid cleaning solution (referred to as lotion) infusion bottles, potassium dichromate is hexavalent chromium ions Cr ~ (+6) of the strong oxidant, and infusion bottle dirt , Most of them are reduced to trivalent chromium ions (Cr ~ (+3)), but there is still unused Cr ~ (+6) in the residual washing solution, which is easily absorbed by the bottle wall and is harder to wash than other foreign matters go with. It is reported that chromium compounds are harmful to humans
