摘要
氰化物是酒类的一项重要安全指标,为了确保白酒质量安全,氰化物含量的准确测定十分重要,主要介绍对GB/T 5009.48—2003中氰化物检测方法的改进,使用紫外可见分光光度计和一次性注射针筒及一次性针孔过滤器对显色后的浑浊液进行过滤,消除白色浑浊物对检测结果的影响。经试验表明,此法操作简便,稳定性好,准确度高。
Cyanide is an important safety index for liquor products. In order to ensure liquor quality, accurate measurement of cyanide content is of vital importance. In this paper, the measurement method of cyanide in GB/T 5009.48-2003 got improved as follows:using UV-visible spec-trophotometer and one-time injection needle tube and disposable pinhole filter to filter the turbid solution after the coloration to eliminate the in-fluence of white turbidity on measurement results.The experiments proved such method was easy to operate with good stability and high accura-cy.
