In this critique, we address multiple shortcomings identified in a recent article published in this journal concerning the adsorption of Pd(II) and Pt(IV) ions from acidic solutions using a novel nanoadsorbent. The identified issues encompass erroneous model equations, unverified adsorption mechanis...
