摘要

以乳糖(La)和二硫化碳(CS2)为原料，在碱性介质中用NaOH/KOH反应合成了两种乳糖黄药LX1和LX2。合成产物用乙醚提取，在空气中干燥，形成黄色液体产物。通过红外光谱和元素分析证实了合成的黄药的形成。合成的黄药用于去除废水中的重金属(CuII和NiII)离子和浊度。结果表明，LX1、LX2和纯乳糖(La)对CuII和NiII的去除率分别为94.9%、95.4%、93.8%、95.4%、73.3%、70.98%。这些结果表明，与文献中报道的许多其他混凝剂相比，LX1, LX2改善了金属和浊度去除。

Synthesis of Disaccharide based Xanthates for the Removal of Some Heavy Metals from Aqueous Solutions

Two samples of lactose xanthates (LX1 and LX2) have been synthesized by the reaction of lactose (La), and carbon disulphides (CS2) in basic medium using NaOH/KOH. The synthesized products were extracted with diethyl ether and dried in air resulting in the formation of yellow coloured liquid products. The formation of synthesized xanthates has been confirmed by FT-IR (IR) spectroscopy and elemental analysis. The synthesized xanthates were utilised for the removal of heavy metal (CuII and NiII) ions and turbidity from wastewater. It was found that, LX1, LX2 and pure lactose (La) removes 94.9%, 95.4%, 93.8%, &95.4%, 73.3%, 70.98% of CuII and NiII respectively. These results show improved metals and turbidity removal with LX1, LX2 in comparison to many other coagulants reported in literature.
