Özet
The aim of the present study is to produce and characterize the activated carbon (AC) material from citrus industrial processing solid residues (CR) under optimized conditions depending on process variables such as chemical impregnation ratio (H3PO4/CR, w/w), carbonization/activation temperature, and time with the phosphoric acid activation and to examine its performance in removing some impurities from water. The optimal AC, which has the surface area of 1090 m(2)/g, the total pore volume of 1.569 cm(3)/g, mesopore contribution of 96.30%, and average pore diameter of 4.93 nm, was produced under these following conditions: 3:1 impregnation ratio (W-H3PO4/W-CR), 500celcius activation temperature, and 1 h activation time. It was characterized by various physicochemical techniques. Furthermore, the adsorptive behavior in water was tested by using Reactive blue 19 (RB19) dye, Diclofenac (DCF) drug, and Pb(II) ions selected as the model adsorbates. Its maximum removal capacity was determined as 370 mg/g for RB19, 181 mg/g for DCF, and 111 mg/g for Pb(II) at 30celcius. This study showed that CR can be used as an effective feedstock in AC production to remove organic and inorganic pollutants from water.
