Abstract: |
Graphite digestion furnace ICP OES was applied to the determination of total Sb in dyeing wastewater. The results showed good linear relationship between emission intensity signal and concentration of Sb in the range of 0~10 mg/L with R value 0.999 5. The method detection limit (MDL) and limit of quantitative determination (LQD) were 0.003 and 0.012 mg/L, respectively. The relative standard deviations (RSD) ranged from 0.17%~2.6%. The recoveries were recorded at a range of 96.1%~103.8%. This method was simple and rapid, and meets the requirement of technical specification. |
