| 摘 要： | 氧化铝冶炼排出的固体粉状废弃物（赤泥）中含有硫酸根离子，用铬酸钡分光光度法测定赤泥中的水溶性硫酸根，在波长420nm处，硫酸根在0～0．12mg／mL范围内与铬酸根吸光度呈线性关系，加标回收率在98％～106％。该法可用于测定赤泥中水溶性硫酸根含量。

| Abstract: | The water-soluble sulfate in red mud discharged from alumina smelting as the waste contains sulfate is determined by barium chromate spectrophotometry.In the wavelength 420 nm,there is a linear relationship between the sulfate concentration and absorbance at the range of 0-0.12 mg / mL.The recovery of standard addition is 98%-106 %,the method can be used for determination of water-soluble sulfate in red mud. |

| Keywords: | red mud water-soluble sulfate barium chromate spectrophotometry |
