摘　　要：尿样经酸化后，用（ＮＨ４）２ＨＰＯ４作基体改进剂，以提高铝的灰化温度，消除干扰。本法简便、快速、精确、灵敏，变异系数为１．８％～５．８％，回收率在９４．４％～１００．８％之间。he sample is acided and using (NH 4) 2HPO 4 as a matrix modifier to increase shing temperature of aluminium and to deduct the disturbance.This method is simple,quick,accurate and sensitive.The RSD is 18% to 58%.The recovery rate is 944%～1008%
