元素碘作为一种化学消毒剂的显著地位已经确立。与其它消毒剂相比元素碘具有抗菌谱最广,在极低浓度如百万分之0.5～2时仍具有极短杀菌时间。有效pH范围广(pH 5.0～9.0),不产生抗药性,且对病毒、真菌和阿米巴原虫亦有杀灭作用。碘消毒剂的有效成份是游离碘,它对感染的治疗和预防是有效的。目前碘附如聚乙烯吡咯烷酮碘(PVP-I_2)已取代元素碘用于临床。然而由于PVP-I_2用于除完好的
The prominent position of elemental iodine as a chemical disinfectant has been established. Elemental iodine has the most extensive antimicrobial spectrum compared to other disinfectants and still has a very short germicidal time at very low concentrations such as 0.5-2 parts per million. Effective pH range (pH 5.0 ~ 9.0), does not produce resistance, and the virus, fungi and amoeba also kill. The active ingredient in iodine disinfectants is free iodine, which is effective in the treatment and prevention of infections. At present iodine with polyvinylpyrrolidone iodine (PVP-I_2) has been replaced by elemental iodine for clinical use. However, due to PVP-I_2 used in addition to intact
