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％。
The sequential chemica sludge combin into seven fractions; wate ed and residual speci spectrophotometry. The RSD 1 extractions have been developed for partitioning of boron in the boron r soluble, ethanol soluble, salt soluble, chelate, sulfate combined, Fe-Mn es. The content of boron in different fractions was determined by was 4.4%（n=4）,and the recovery was 91.7%-102.4%.
