用途: Sulfathiazole is an organosulfur compound that has been used as a short-acting sulfa drug.Target: AntibacterialSulfathiazole (20 μg/L) starts to be degraded between day 31 and day 38 in one of the two batch reactors containing different wastewater matrices. Sulfathiazole is degraded at a substantially faster rate than sulfamethoxazole or sulfamethazine in the nitrification process (S3) [1]. Recovery from spiked manure slurry samples is 64% for Sulfathiazole at pH 9. Sulfathiazole has acidity constant of pKa of 7.1and retention times (tR) of 7.8. S/N values for Sulfathiazole are above 100 at the 1 mg/kg level [2]. Sulfathiazole sorption to inorganic sorbents exhibits pronounced pH dependence consistent with sorbate speciation and sorbent charge properties. Sulfathiazole cations are most important for sorption to clay minerals, followed by neutral species [3]. 作用: 磺胺噻唑是一种有机硫化合物,已被用作短效磺胺药。 目标:抗菌磺胺噻唑(20μg/ L)在含有不同废水基质的两个间歇反应器之一的第31天和第38天之间开始降解。 在硝化过程中,磺胺噻唑以比磺胺甲恶唑或磺胺二甲嘧啶快得多的速度降解(S3)。 在pH9下,磺胺噻唑的加标粪浆样品回收率为64%。磺胺噻唑的酸度常数pKa为7.1,保留时间(tR)为7.8。 磺胺噻唑的S / N值在1 mg / kg水平时高于100。 磺胺噻唑对无机吸附剂的吸附表现出明显的pH依赖性,与吸附物的形态和吸附剂电荷特性一致。 磺胺噻唑阳离子对粘土矿物的吸附最重要,其次是中性物种。 物理化学性质: CAS号:72-14-0 常用中文名:磺胺噻唑 常用英文名:Sulfathiazole 分子式:C9H9N3O2S2 分子量:255.317 密度:1.6±0.1 g/cm3 沸点:479.5±47.0 °C at 760 mmHg 熔点:202.5ºC 闪点:243.8±29.3 °C 储存条件:0-6°C |
