Pollution of water is a pragmatic problem in the world today. Contamination by heavy metals and dyes is a major concern of water pollution. This study examines a new adsorbent made by the reaction between para-nitroacetanilide and concentrated sulfuric acid and is the first-ever study carried out to the best of our knowledge. The adsorption of Cu 2+ has been studied on this adsorbent as a preliminary study. The prepared material was characterized using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-ray Fluorescence Spectroscopy (XRF), Powder X-ray Diffraction (PXRD) and point of zero charges (pzc) analysis. The average pore diameter obtained from SEM analysis was 2 μm, concluding that the adsorbent has a desirable morphology for better adsorption. The adsorption experiments were carried out as a function of pH, shaking time, initial Cu 2+ concentration, and adsorbent dosage. The adsorption kinetics at low concentrations (34.50 mg L -1 = 1.5 10 -7 mol m -3 ) follows pseudo-second-order kinetics with an R 2 value of 0.99, suggesting a chemisorption process. The adsorption data agree with the Freundlich isotherm at higher concentrations (varying from 17.21 mg L -1 (7 10 -8 mol m -3 ) to 96.25 mg L -1 (3.6 10 -7 mol m -3 ) revealing multilayer adsorption, amounting to a maximum adsorption capacity of 8.31 mg g -1 at 25 ̊ C.
