在分散度不同的区域内进行区域采样用于水中硫酸根离子的测定,结果令人满意。应用此方法测定硫酸根离子的线性范围为200.0~3000mg/L;进样频率为120次/h;相对标准偏差为1.70%
Regional sampling in areas with different degrees of dispersion for the determination of sulfate in water was satisfactory. The linear range of sulfate ion was 200.0 ~ 3000mg / L. The sampling frequency was 120 times / h. The relative standard deviation was 1.70%
