摘要
报道了采用试样自身色泽补偿和氯化物标准加入法,在试样最小吸收波长600nm处测量表观吸光度代替测量浊度的方法,测定了重铬酸镁中的氯化物含量.方法简便,结果较好。
A turbidimetric method for the determination of chloride in colored sample solution of MgCr_2O_7 was developed. Measurement of apparent absorbance instead of turbidity was carried out at wavelength of 600 nm in compensation for the influence of the sample color on the measurement. A procedure of standard additions was used for the determination of the chloride content in MgCr_2O_7.
