ANALYSIS AND EVALUATION THE IRON AND ZINC CONTENT IN WHITE LEG SHRIMP (LITOPENAEUS VANNAMEI) AT TRUNG TRACH COMMUNE, BO TRACH DISTRICT, QUANG BINH PROVINCE

Abstract

The atomic absorption spectrophotometric method flame (F-AAS) is applied to determine the iron and zinc content in white leg shrimp at Trung Trach commune Bo Trach district - Quang Binh province. This method has high repeatability with RSD < 2,38%, and the recovery from 95,7 % to 103,8%, and low limit of detection. This result shows that the average iron and zinc content in white leg shrimp is relatively high (7,44 ÷ 35,80 mg/kg fresh and 7,63 ÷ 20,05 mg/kg fresh) and within the allowed limits according to the regulation No. 46/MOH 2007.
