The present invention relates to a method of detoxifying sulfur for fodder to use toxicity-removed detoxified sulfur as an additive for feedstuff. A conventional method of detoxifying sulfur has had problems that large amounts of various organic and inorganic raw materials are required, and a process of pretreating the raw materials is cumbersome in order to remove toxicity of sulfur. Therefore, the present invention provides a detoxifying method which is capable of effectively removing harmful components only by using a surfactant and a chelating agent as a method of improving the problems of the conventional sulfur detoxifying method. A preparation method of detoxified sulfur of the present invention comprises mixing and stirring 100 parts by weight of water with 10 to 20 parts by weight of inorganic sulfur, 2 to 5 parts by weight of the surfactant, and 3 to 5 parts by weight of the chelating agent at room temperature in order to remove toxicity of sulfur. The preparation method according to the present invention has its significance in commercializing detoxified sulfur for feedstuff by securing a mass production technology of high purity detoxified sulfur while increasing economic efficiency by simplifying a conventional complicated preparation process by using cleaning and emulsifying functions of the surfactant and a metal ion blocking effect of the chelating agent. Further, the preparation method according to the present invention promotes the convenience of the users and is able to contribute to the production of high value-added agricultural and stockbreeding products by providing a high concentration particulate sulfur dispersion in a stable water dispersible form to enable users to easily use sulfur.COPYRIGHT KIPO 2018본 발명은 사료용 유황제독방법에 관한 것으로 독성이 제거된 법제유황을 가축사료용 첨가제로 사용하고자 하는 것이다. 종래의 유황의 법제 방법은 유황의 독성을 제거하기 위해 다량의 유기, 무기 여러 가지 원료들이 필요하고 또한 원료의 전처리 공정이 번거로운 점이 있었다. 이에 본 발명은 종래의 유황제독방법의 문제점을 개선하는 방법으로 계면활성제와 킬레이팅제를 이용하여 유해성분만을 효과적으로 제거할 수 있는 법제방법을 제공한다.계면활성
