Modification of Klein's wet ashing procedure for determination of mercury.
An investigation of the use of HCl in Klein's method (25.108-25.115) to prevent loss of mercury during wet digestion resulted in consistently good recoveries from jowar and fish samples. Recoveries for the modified method ranged from 90.9 to 97.0% compared with 14.4 to 35.5% for the original method.
