大孔树脂问世以来,在许多领域已有广泛应用。本工作的目的是合成一种具有合适孔结构的大孔强碱性阴离子交换树脂,用以处理铀矿山废水。本文介绍了260树脂的合成方法及其性能。工艺试验表明,用该树脂从矿山废水中提取铀时,吸附快、容量高,易淋洗再生。260树脂的性能与美国 Amberlite IRA900树脂的性能相近,司望在其它一些场合推广应用。
Since the advent of macroporous resin, it has been widely used in many fields. The purpose of this work is to synthesize a macroporous strong base anion exchange resin with a suitable pore structure for the treatment of uranium mine wastewater. This paper introduces the synthesis of 260 resin and its performance. Technological tests show that when the resin is used to extract uranium from mine waste water, it has the advantages of fast adsorption, high capacity and easy elution and regeneration. 260 resin performance and the United States Amberlite IRA900 resin similar performance, Division hope in some other occasions to promote the use of.
