Optimisation Of Digestion Method For Determination Of Arsenic In Shrimp Paste Sample Using Atomic Absorption Spectrometry

The microwave digestion method was developed and verified for the determination of arsenic in shrimp paste samples. Experimental design for five factors (HNO3 and H2O2 volumes, sample weight, microwave power and digestion time) were used for the optimisation of sample digestion. For this purpose, tw...
