The present invention relates to a method of preparing the povidone-iodine sol in a form of a povidone-iodine gel by adding a gelatin to a povidone-iodine sol containing nonvolatile solvents as plant extracts such as canola oil, olive oil, grape seed oil, edible oil, corn oil and the like in a povidone-iodine complex prepared by drying a mixture of povidone and iodine in a vacuum state of 42 to 72°；C. The purpose of the present invention is to provide a method of preparing the povidone-iodine sol in the form of the povidone-iodine gel to solve a disadvantage that the povidone-iodine sol flows down, the povidone-iodine sol, as a human body bactericidal disinfectant, containing the nonvolatile solvents as the plant extracts such as canola oil, olive oil, grape seed oil, edible oil, corn oil and the like in the povidone-iodine complex prepared by drying the mixture of povidone and iodine in the vacuum state of 42 to 72°；C. The method of the present invention comprises preparing the povidone-iodine sol in the form of the povidone-iodine gel by adding the gelatin to the povidone-iodine sol containing the nonvolatile solvents as the plant extracts such as canola oil, olive oil, grape seed oil, edible oil, corn oil and the like in the povidone-iodine complex prepared by drying the mixture of povidone and iodine in the vacuum state of 42 to 72°；C. Therefore, the method according to the present invention not only prevents the povidone-iodine sol from being flown down, but also proves wide sterilization effects in adenovirus, norovirus, avian influenza virus, super bacteria, tuberculous bacillus and the like, exhibits a sterilization effect of 99.99% in Ebola virus, and has strong human body sterilizing and disinfecting effects in antivirus of SARS coronavirus that are the same series as MERS virus or coronavirus by strong oxidizing power of ions of the povidone-iodine gel.COPYRIGHT KIPO 2018[기술분야]포비돈과 요오드의 혼합물을 42℃~72℃의 진공상태에서 건조시켜서 만든 포요드 복합물에 식물 추출물인 비휘발성 용제들 카놀
