氢化端羟基液体丁腈橡胶中残留铑催化剂的回收

研究了大孔离子交换树脂对氢化端羟基液体丁腈橡胶（HHTLNBR）胶液中残留铑催化剂的吸附和解吸附性能,考察了不同类型树脂、树脂用量、吸附温度及时间对吸附率的影响,对筛选出的树脂进行了解吸附条件试验,并对树脂吸附前后的HHTLNBR的结构进行了表征.结果表明,用带有伯氨基的大孔离子交换树脂（D4）作为吸附树脂,在温度为80℃、用量为2.0 g、反应时间为2h的条件下,对铑的吸附率可达98.0％以上;采用质量分数为10％的硫脲-甲酸溶液（以质量分数为88％的甲酸配制）作解吸剂,在80℃下反应1h,解吸率约为70.0％;用D4脱除铑催化剂的过程并未对HHTLNBR的结构产生影响....
