A new method is described for gravimetric determination of gold as tetra phyenlarsnium aurichloride, (C6H5)4As, AuCl4. Accuracies ranged from 0.4% to 0.60% for sample sizes between 0.2 and 4mg., with Analytical Factor FAu=0.2728.
This method is used for analyse of metallic aurates with their prepration and thermolysis.
