Comparison of performance between the standard and modified method in the determination of mercury in fish chips of Terengganu

Abstract

The study was conducted to evaluate the modified method and standard method for the determination of mercury in "keropok keping" and "keropok lekor". The samples were analyzed by using Cold Vapor -Atomic Absorption Spectrometry (CV-AAS). Several parameters were evaluated for both methods such as linearity, precision, accuracy and detection limit. The certified reference material used was DOL T-2 (DogFish Liver).The parameter shows better precision and accuracy for the modified method than standard method in the determination of mercury content in keropok lekor.
