In this study, the novel activated carbon developed from fruit stone, through hydrothermal treatment at low pressure and temperature, was utilized for the removal of 4-nitrophenol, 4-chlorophenol, and phenol from water. The activated carbon produced (AC-HTPEFS) showed a well-developed porosity with a surface area of 569 m g and a total pore volume of 0.342 cm g.

- * The research optimized various factors like contact time, temperature, and initial metal concentration, achieving 80% removal of both metals within 60 minutes at an optimal pH of 6.
- * Results indicated that the adsorption process was endothermic, spontaneous, and indicated strong interactions between the adsorbent and the metals, suggesting that fruit stone could effectively be used for cleaning up other toxic substances as well.
Cellulose: A review as natural, modified and activated carbon adsorbent.
Bioresour Technol
September 2016
Cellulose is a biodegradable, renewable, non-meltable polymer which is insoluble in most solvents due to hydrogen bonding and crystallinity. Natural cellulose shows lower adsorption capacity as compared to modified cellulose and its capacity can be enhanced by modification usually by chemicals. This review focuses on the utilization of cellulose as an adsorbent in natural/modified form or as a precursor for activated carbon (AC) for adsorbing substances from water.
