In addition, the heavy metal retention isotherm over a wide range of concentrations for the bentonite follows Temkin and Langmuir adsorption models while Freundlich and Langmuir models for the kaolin. Interestingly, at a high concentration of 10 mM, the Pb precipitation unlikely occurs in the presence of both clays tested over a wide range pH level (< 10), whereas it likely takes place in case of Cu and Zn.]]> Sat 24 Mar 2018 07:09:39 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51791 Mon 18 Sep 2023 15:18:56 AEST ]]>
