Study on Rapid Spectrophotometric Method for Determination of Fe,Mn,Zn and Cu in biological Sample

Zhou Zhenyi;Yin Tianshou (Anhui Agrotechnical Teachers'College, Fengyang 233100)  
A rapid spectrophotometric method for determination of Fe,Mn,Zn and Cu in biological sample is proposed. Themethod is based on HNO3-HClO4 method for sample digestion, 2, 2'-dipyridyl method for Fe determination, 5-Br -PADAP method for Mn determination,Zn(HD2)2 mixed colour methed with once solvent extraction for Cu determination.Time required for a sample analysys is about 2-3hrs in general exclusive of the process of sample digestion.
