【Abstract】 The four hundred and sixty four hair samples were analyzed by ICP-AES. The effects of several washing detergents on the determination of elements in hair samples were compared. Using addition recovery method, the recovery rates were obtained and the relative standard deviations also obtained with a parallel experiment and a multi-measure-accumulate-statistics method.更多还原
