Adsorption is a simple, inexpensive, and common practice in water purification and recycling technologies. Therefore, researchers investigated various approaches and materials to develop low-cost adsorbents. Furthermore, researchers investigated using local materials to develop chemically activated carbon that is capable of removing contaminants from water. This study aims to evaluate the preliminary use of olive pit (OP) derived activated carbon for water treatment from Methylene Blue MB. The effectiveness of olive pits as a pollutant's adsorbent was investigated under various activation conditions (i.e., particle size, pH, temperature, natural water, distilled water) and using two activating agents: H
3 PO4 and H2 SO4 . In total, two samples were investigated; the adsorption process attained equilibrium between 60 min and 120 min, while the results indicated the best performance achieved (i.e., highest absorption) at a size of 0.6 mm, a temperature of 30 °C, and a base medium (i.e., a pH equal to 8.06). Furthermore, it was found that the natural matter present in natural spring water is responsible for competitive adsorption effects; thus, distilled water had better results. This sample was prepared with olive pits prepared with H3 PO4 . [ABSTRACT FROM AUTHOR]- Published
