Description
We studied the wet-ashing condition and found a proper method for the decomposition of organoarsenic without using a closed microwave digestion oven system. The hydride generation technique is incapable of detecting organoarsenic, such as arsenobetaine and arsenocholine without decomposition. However, organoarsenic is hard to be decomposed by the conventional wet-ashing method. Therefore we developed open wet-ashing conditions and found optimized conditions (HNO3-H2SO4-HClO4 at 400°C or higher without dryness) to completely decompose organoarsenic.
