ICP-MS测定醋酸酯淀粉中7种元素含量
Determination of 7 Kinds of Elements in Starch Acetate by ICP-MS
摘要
Abstract
Seven kinds of elements in starch acetate were determined by inductively coupled Plasma-mass spectrum(ICP-MS). Three pretreatment methods including dry, wet and microwave digestion methods were compared. It was showed that microwave digestion method was high-efficient, stable, with high recovery rate. Starch acetate was pretreated by microwave digestion and seven kinds of elements in starch acetate were determined by ICP-MS, including boron, aluminum, chromium, nickel, arsenic, cadmium, lead. The results showed that the linear range of the method was wide, linear correlation coefficient(r) wsa more than 0.9997, recovery was more than 92.0%, RSD was lower than 3.8%. The method was simple, fast, sensitive and accurate, and achieved satisfactory results in the analysis of starch acetate. It was indicated that in starch acetate, aluminum content was between 4 mg/kg and 7 mg/kg, and others were less than 2 mg/kg.关键词
