Abstract Potentially toxic elements like Cr +6 and Ni +2 cause severe health hazards. Therefore, the current work was aimed at cleaning water using Prosopis glandulosa raw sawdust (SD) its derived biochar (AC). Both adsorbents were characterized via SEM, FTIR spectroscopy, EDX, TGA applied for effective removal of Ni( ii ) Cr( vi optimum values experimental conditions, mechanism assessed adsorption isotherm kinetic models. The correlation coefficient R 2 confirmed pseudo-second-order kinetics preferred Freundlich model. Maximum iv obtained a pH 4.0, bio-sorbent concentration 0.8 g·L −1 , temperature 50°C 50 min with metal 110 ppm, while maximum contact time 70 130 ppm in above-mentioned conditions. results isotherms model revealed that processes involved multilayer formation on biosorbent’s heterogeneous surface. Also, their thermodynamic investigation showed process is spontaneous exothermic and, therefore, can be effectively utilized to remove from water.
