摘　　要：对悬液法与载体法检测ＴＤ清洗消毒剂（主要成分为氯化磷酸三钠）破坏ＨＢｓＡｇ的效果进行比较。结果，在 ２０℃，对悬液中 ＨＢｓＡｇ，仅需含有效氯 ４００ ｍｇ／ Ｌ的该消毒剂溶液作用 ２ ｍｉｎ，或含有效氯３００ ｍｇ／Ｌ者作用３ ｍｉｎ，即可将ＨＢｓＡｇ抗原性破坏；对不锈钢表面ＨＢｓＡｇ，需含有效氯１０００ ｍｇ／Ｌ该液作用 １０ ｍｉｎ，或含有效氯 ５００ ｍｇ／ Ｌ者作用 １５ ｍｉｎ才可。说明破坏不锈钢表面 ＨＢｓＡｇ抗原性较悬液中者难。Suspension method and carrier method for examination of efficacy of TD disinfecting detergent (the main ingredient was chlorinated trisodium phosphate) in destroying HBsAg were compared. The results showed that at 20℃, the solutinn of this disinfectant containing available chlorine 400 mg / L with a 2 min contact time or the solution containing available chlorine 300 mg/ L with a 3 min contact time could destroy the antigenicity of HBsAg in suspension, while the solution containing available chlorine 1000 mg / L with a 10 min contact time or the solution containing available chlorine 500 mg / L with a 15 min contact time was required for destroying HBsAg on stainless steel surface, indicating that it was more difficult to destroy the antigenicity of HBsAg on stainless steel surface than that in suspension.
