Adsorption of metal ions and dyes from aqueous solutions using lala clam (Paphia textile) shell (IR)

This study aimed to evaluate the effectiveness of lala clam shell as an adsorbent for the remediation of water contaminated by metal ions and dyes. Three main studies, namely adsorption, desorption and characterisation, have been conducted. In this study, Cd(II), Cu(II), Pb(II), Congo red (CR), Meth...
