作者用电位测定进行定量分析的方法,研究直流电碘离子导入人体的量。两个海绵衬垫用无矿质水洗三遍后,将1%KI 溶液10ml 灌注于阴极海绵.膝关节内外侧对置,海绵面积50cm~2,电流强度10mA,通电20分钟.导入后,用重蒸溜水分别将阴阳极海绵充分消洗,洗出液进行电位测定和定量分析。结果表明,阴极海绵碘的回收率,通电的为81.6～84.3%,不通电的为98.5～98.8%,说明只是在也流的作用下碘才进入人体。阳极海绵只含有极微最 The authors use the method of quantitative analysis of potential measurement to study the amount of DCI that is introduced into the human body. Two sponge liners were washed three times with mineral-free water, and 10 ml of 1% KI solution was poured on the cathode sponge. The inside and outside of the knee joint were opposite, the sponge area was 50 cm 2, the current intensity was 10 mA, and the power was applied for 20 minutes. Distilled water, respectively, the negative anode sponge full wash, washing liquid for potential measurement and quantitative analysis. The results showed that the recovery rate of cathodic sponge iodine was 81.6-84.3% when energized and 98.5-98.8% when not electrified, which indicated that iodine entered the human body only under the action of flowing current. Anode sponge contains only the most minimal
