摘要
食用酒精重金属检验方法目前是采用饱和硫化氢溶液作显色剂的比色测定法,该法毒性大、气味难闻、污染严重、繁琐、耗时。研究了采用硫化钠溶液取代硫化氢作为显色剂的可行性,并确定了最佳的测定条件。与原来的方法相比,本法极大地降低了毒性,大大减少了污染、而且简便、快捷、易于操作。本法适用于食用酒精质量管理中重金属指标的分析检验。
The current test method of heavy metals in edible alcohol is adopted colorimetric method using hydrogen sulphide saturated solution as colorific agent, this method is toxic, disagreeable odour, contaminated, overlaborated and time expended. A new method was introduced in this paper： the practability of adopting sodium sulphide instead of hydrogen sulphide for colorific agent has been studied and determinated the optium test condition. As compare to the current method, the new method decreases the toxic and contaminant enormoursly,and in addition,has the avantage of simple, rapid and easy to operate. This method is suitable for the test of heavy metals in the quality control of edible alcohol.
