Abstract
In this study, the efficiency of activated carbon prepared from pineapple skin(ACPS) in removing safranin T (ST) dye from aqueous solution was examined. ACPS was prepared through phosphoric acid chemical activation processes (ACPS-H3PO4 ) and at a temperature of 300 °C foe 2 hr. The results obtained from the preparation process indicate that the prepared ACPS-H3PO4 has high surface properties and porosity for use as a highly efficient absorbent material. The prepared surface was characterized by techniques XRD, FESEM, EDX and TEM. The maximum efficiency (84.84%) and absorption (168.73 mg/g) of ACPS-H3PO4 for ST dye removal was achieved under the following conditions: ACPS-H3PO4 dose = 0.05 g/L, CT dye concentration = 100 mg/L, pH = 7,equlibruim time = 60 min, temperature = 25°C. It was found that the isotherm data matched the Freundlich isotherm with high accuracy values. The much higher adsorption capacity of ACPS-H3PO4 for the dye (168.73 mg/g) compared to other previously used sorbents with excellent regeneration level (five cycles) depicts the superior performance of ACPS-H3PO4 in adsorption systems.
