弱碱性离子交换树脂从钼冶炼废酸中回收铼的研究
Investigations on Recycling Rhenium from the Waste Acid of Molybdenum Smelting by Weak Base Ion Exchange Resin
摘要
Abstract
This paper investigated the adsorption and desorption properties of recycling rhenium from molybdenum smelting waste acid by weak base ion exchange resin .The effects of Cl -resin and SO4 2-resin on adsorption properties of rhenium were studied by static tests .The results indica-ted that rhenium adsorption rates of Cl -resin and SO4 2-resin were 82.29%and 82.23%, respec-tively.Meanwhile, the kinetics properties verified that the limiting step of rhenium adsorption process was the diffusion process of ReO 4 -ions.Furthermore , the effects of ammonia concentration and sodium hydroxide concentration on rhenium desorption properties were investigated .The results showed that rhenium desorption rate and reaction rate of the desorption process both increased with increasing the eluent concentration .The tests of FTIR and EPMA verified that 2 .5% sodium hy-droxide solution could effectively desorb rhenium from loaded resin .关键词
