Adsorption of malachite green from polyaniline facilitated cobalt phosphate nanocomposite from aqueous solution

SK Ben, S Gupta, KK Raj, V Chandra - Chemical Physics Letters, 2023 - Elsevier
Synthetic dyes are significant environmental issues brought on by the release of coloured
effluent into the hydrosphere. In our study, we employed polyaniline functionalized cobalt
phosphate for adsorption of cationic dye malachite green from an aqueous solution. The
adsorption capacity of the adsorbents towards MG was found in the order of PANI< CoP<
CoP@ PANI nanocomposites at room temperature and pH 7. The MG adsorption process
followed the pseudo-second-order kinetics (R 2≥ 0.99). The maximum adsorption capacity …
