| Abstract: | Sample is dissolved by acid. Gold can be assembled by the foam-plastics'absorption, oscillation and separation. The interference elements are covered by EDTA-(NH4)3C6H5O7.2Hs2O. If pH=3, TMK and gold become the red complex. Choose the proper system and control reagent amount and then proceed mutually small physical volume in water SP. If sensitivityr= 1.25 * 105, take and weigh 10 grams of sample, gold for 0.001 g/t above can be measured. |
