林可霉素药物电极的制作及应用

The membrane electrode modified with lincomycin-Bi（Ⅲ）was reported. The electroactive material was the complesation of Bi（Ⅲ）ion and lincomycin in the mole ratio of 1∶1,the influences of various factors on the properties of electrode were studied,both good calibration curve and wide detection ran ge of 4 orders were obtained. The limit of detection was about 10-5mol/L of lincomycin. More than ten kinds of inorganic and some other substances have little interference on the detection of lincomycin. The electrode could be used directly to analyze lincomycin by potentiometry.

树脂的再生处理

201×4型阴离子交换树脂在使用后,需通过再生恢复活性。传统的再生方法用酸、碱、盐处理,新方法用次氯酸钠、碱处理。用于硫酸庆大霉素生产中,新法较传统方法科学、经济、环保。

高分子吸附树脂与酸性材料配施对盐碱离子钝化效果研究

针对河套地区氯化物型盐碱土的特点,通过室内土壤改良试验,研究了201×4强碱性苯乙烯系阴离子交换树脂与3种酸性材料(腐殖酸、泥炭、磷酸一铵)配施对盐碱土盐碱离子的吸附钝化效果。结果表明:在201×4树脂施用量为2%时,其与泥炭1.0∶1.5比例配施改良效果较为突出,较对照土壤水溶性Na^+含量下降了21.41%,水溶性Cl^-含量下降了34.36%,水溶性SO_4^(2-)含量下降了87.88%,全盐含量下降了30.64%,较单施201×4树脂土壤pH值下降了0.78,可以作为今后盐碱土改良剂配方材料。
