  • 摘要: 实验定量研究了存在Ca2+、Mg2+和Fe3+时,应用高碘酸钾分光光度法测定Mn2+的准确性,旨在探讨应用该方法准确测定电解锰渣中Mn(Ⅱ)的可行性。结果发现Ca2+浓度超过320 mg/L时,测定过程中会产生大量絮状乳白色沉淀,对Mn2+的测定结果产生干扰。经过16 h的自然沉降,干扰被彻底消除。Mg2+在浓度为0~192 mg/L范围内对Mn2+浓度的测定不产生干扰。同时,Fe3+的存在对Mn2+浓度的测定产生灵敏的干扰,使用掩蔽剂氟化钾可以减少Fe3+的干扰,但却不能彻底消除Fe3+的干扰。提出了在电解锰行业中,没有彻底地消除Ca(Ⅱ)或Fe(Ⅲ)的干扰因素前,需要更为精确地测定Mn(Ⅱ)的浓度,不建议使用高碘酸钾分光光度法。
    Abstract: To investigate the feasibility of the potassium periodate spectrophotometric method accurately determining the Mn(Ⅱ) concentration of electrolytic manganese residues, the interference of Ca2+,Mg2+,Fe3+ was studied. The results showed that the determination process produced large of flocculent milky white precipitate when Ca2+ concentration exceeded by 320 mg/L. And the precipitate interfered in the results. However, after 16 hours of natural subsidence, the interference of Ca2+ was completely eliminated. Mg2+ didn't interfere in the result. Fe3+ produced sensitive interference. Meanwhile, the results of interference cancellation showed that masking agent potassium fluoride couldn't entirely eliminate the interference of Fe3+. Therefore, we can't directly apply potassium periodate spectrophotometric method to accurately determine the Mn(Ⅱ) concentration in electrolytic manganese residues without effectively eliminating the interference of Ca(Ⅱ) or Fe(Ⅲ).
