| 摘 要： | 采用连续浸提法将硼泥中的硼划分为七种物理形态,即:水溶态、醇溶态、盐溶态、络合态、硫酸盐等结合态、Fe-Mn结合态及残渣态。用分光光度法测定各形态硼的含量。测定结果的相对标准偏差为4.4%(n=4),回收率为91.7%~102.4%。

| Abstract: | The sequential chemical extractions have been developed for partitioning of boron in the boron sludge into seven fractions: water soluble,ethanol soluble,salt soluble,chelate,sulfate combined,Fe-Mn combined and residual species.The content of boron in different fractions was determined by spectrophotometry.The RSD was 4.4%(n=4),and the recovery was 91.7%~102.4%. |
