Abstract
This paper focuses on the method for determining tungsten and molybdenum content in tungsten concentrate.The tungsten concentrate sample is dissolved using a mixed solution of sulfuric acid and phosphoric acid to form a stable solution containing soluble tungsten,molybdenum,and other elements.Subsequently,inductively coupled plasma optical emission spectrometry(ICP-OES)is employed for detection,accurately determining the tungsten and molybdenum content based on their characteristic spectra.The results indicate that the tungsten and molybdenum content in the test solution is measured in a system of 5%hydrochloric acid-0.2 g/L tartaric acid-1%phosphoric acid,with relative standard deviations(RSD,n=11)ranging from 0.22%to 4.4%and spiked recoveries be-tween 97.6%and 100.7%.The determination ranges are 0.039～150.00 μg/mL for tungsten and 0.009～20.00 μg/mL for molybde-num.This method is simple,rapid,cost-effective,and consumes minimal materials,making it suitable for determining tungsten and molybdenum content in tungsten concentrate.关键词
