Effects of organic acids on Eu(III) sorption on Na

2014-11-1  Acetic acid, citric acid, oxalic acid, salicylic acid are the typical representatives of root secreta, which may modify the retention of heavy metals. Moreover, simple organic acids themselves are sometimes pollutants and co-exist with heavy metals in the environment [17–25]. For these reasons, it is significant to study the effects of organic acids on heavy metals sorption.
