Abstract
The memory effect of silver and aqua regia in the vessel by their permeation was studied during the microwave digestion of samples under the operating conditions of high temperature and pressure. The extent of permeation in vessels with the solution containing silver 5 mg has been shown to be <TEX>$0.97{\mu}g/mL$</TEX> for the digestion of <TEX>$HNO_3$</TEX> solution and <TEX>$0.47{\mu}g/mL$</TEX> for the digestion of oil sample under condition of MDS 180T program (<TEX>$180^{\circ}C$</TEX>, 220 psi).
