O knihe
Date seed activated carbon (DSAC) was created from date seed powder using a chemical activation procedure including potassium hydroxide (1:1 weight ratio) as the activating agent and temperatures ranging from 500 to 700 oC. Powder X-Ray diffraction was used to describe the activated carbon that resulted. XRD patterns revealed amorphous carbon structure, and scanning electron microscopy was used to examine the surface morphology of DSAC. Iodine adsorption properties of date seed-derived activated carbon was good, with an iodine number value of 798 mg/g, which is substantially greater than commercial activated carbon. In order to identify ideal adsorption conditions of malachite green (MG) from aqueous solutions, variables such as starting pH, adsorbent dosage, contact time, and temperature have all been examined. The Langmuir isotherm was found to appropriate the experimental results well. The dye uptake mechanism was described using the pseudo-second-order rate expression. The activation energy of adsorption was likewise found to be 14 kJ.mol-1, representing that the adsorption is chemisorption.
