摘要
Abstract
A method is developed to detect sodium thiosulfate in raw milk. In the weak acidic medium, hypochlorite in sample reacted with potassium iodide to form free iodine which was then titrated with the standard solution of sodium thiosulfate, using starch solution as indicator, to calculate the content of chlorine.The approach is simple and easy to operate, high recovery ratio and low cost, analysis period is short, so it can be used as a rapid detection method of ammonia nitrogen in raw milk.关键词
