摘要
Abstract
A highly sensitive spectrophotometric method is described for the determination of phosphorus based on the ion-associate B in the presence of PVA-124.The maximum absorption of the ion-associate complexes is at 580nm.It is according with Bill law when P concentration is 0.02~0.08mg/L.The apparent molar absorption coefficient is 1.87×105L*mol-1*cm-1.关键词
