“…Properties of MZTWAC. The SEM exhibited in Figure 1 MZTWAC reveals the availability of irregular and porous surface that facilitates the adsorption process to take place [20]. From Figure 2 [19], it is visible that MZTWAC possessed broad peaks, -OH stretching from hydroxyl to phenolic groups [28][29][30], C-H stretching of aliphatic acids, C-O stretching of alcohols [28,29], and C-O stretching of carboxylic acid [7] and alcohols.…”

“…Activated carbon was prepared from Manilkara zapota tree wood. The process remained encrypted in the authors' original article [20]. To get to know the presence of functional groups that favour chromium(VI) ion adsorption and to have an idea on the surface morphology, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analysis were performed.…”

“…Existing study gave attention to synthesis of derivative, an activated carbon from Manilkara zapota tree wood treated with citric acid [19] to treat chromium(VI) ion-polluted water batch adsorption mode. Wood pieces of Manilkara zapota tree wood [19,20] were gathered. Optimum conditions for process variables, for instance, initial concentration of chromium(VI), pH, contact time of the experiment, and MZTWAC (adsorbent) dosage, were tested through a rotatable central composite design under response surface methodology with support of software version 7, namely, Design Expert.…”

The current paper makes obvious the elimination of chromium(VI) ion, from wastewater via adsorption technique with activated carbon generated from Manilkara zapota tree (MZTWAC). Preliminarily MZTWAC has undergone characterization studies which uncovered the suitability of MZTWAC to expel chromium(VI) from aqueous solution. Batch adsorption experimentation was premeditated with the competence of central composite design (CCD) and it was executed. Response surface methodology (RSM) was the key optimization software to appraise the adsorptive chattels of MZTWAC engaged in removing chromium(VI) ion in aqueous solution which explored the interactions flanked between four expounding variables explicitly initial concentration of chromium(VI) ion, pH of the solution, MZTWAC dose and time of exposure, and contact time. The response variable that was concentrated in the study was adsorption capacity. It was deduced a polynomial in quadratic equation was documented amid the adsorption capacity and variables influencing the adsorption with R 2 = 0.9792 which was projected as the best suit for the adsorption process. ANOVA that is expanded as analysis of variance judged the connotation of adsorption process variables. 0.2 g of MZTWAC dosage has removed 87.629% chromium(VI) from aqueous solution. The enhancement of adsorption process reclined on the attainment of maximum adsorption capacity which further depends on the optimization of variables under consideration. This criterion was accomplished by the desirability function optimizing the process variables.
