| Abstract: | Based on synthetical study on determing trace arsenic in orsenic substances, a combined rne-thod of the arsenic stain with the Ag-DDTC was adopted. The empheasis was two improvements on the Ag-DDTC methed. The experiments inducated that the novel method had advantages of quickness and accuracy. |
