摘　　要：以交联淀粉作载体，制备出紫蓝色、直径约100μm、不溶于水的交联淀粉碘（CSI）颗粒，有效碘含量为6．393mg／1000mg。以该消毒剂15g／L作用3min，对菌悬液中大肠杆菌与伤寒杆菌的杀灭率为100％。对自来水以5g／L作用5min，泉水、地面水以50g／L作用25～30min，可将细菌总数减少99．73％以上。反复回收3次的消毒剂，杀菌效果无明显变化。The water-insoluble cross-linked starch iodine (CSI) was prepared using the cross-linked starch (CS) as the carrier of iodine. CSI is purplish blue-colored granules with diameter about 10 μm and contains available iodine 6.393 mg/ 1000 mg. It shows strong aborption Peak at 300~900 nm wavelength of ultrviolet rays. CSI 15g/L with a 3 min contact time killed 100% of Escherichia coli or Salmonella typhi. CSI 5g /L with a 5 min contact time, CSI 50 g / L with a 25 min contact time and CSI 50 g / L with a 30 min contact time could kill 99.73% ~ 99.94% of natural bacteria in tap water, fountain water and surface water respectively. The efficacy of CSI recovered repeatedly 3 times in killing E. colt in water did not change obviously.
