In this work, the use of agricultural waste from oil palm petioles (OPP) as a raw material for the production of activated carbon (AC) and its characterization were examined. By soaking these chars in nitric acid (HNO3) and potassium hydroxide (KOH) at a 10% concentration, AC with favorable high-porosity carbons was generated. To maximize AC synthesis, the AC was pyrolyzed at 460, 480, and 500 °C temperatures for 20 min. Based on micrographs of formed pores and surface functional groups, 480 °C carbonization temperature on both chemical HNO3 and KOH was shown to be the best. The FTIR measurements reveal that chemical activation successfully transformed the raw material into AC. Moreover, FESEM micrographs show the pores and cavities of the prepared AC achieve a high surface area. This is further supported by BET results of HNO3 OPP AC and KOH OPP AC with surface areas of 883.3 and 372.4 m2/g, respectively, compared with the surface area of raw OPP of 0.58 m2/g. Furthermore, the tests were revealed by an optimization model, namely response surface methodology (RSM), using a central composite design (CCD) technique. The findings showed that all three parameters (pH, time, and dose) had a substantial impact on the removal of Zn, Fe, and Mn. Analysis of variance (ANOVA) and analytical error indicated that the models were accurate, with a low error value and a high R2 > 0.9. Remarkably, the good correlation between actual and predicted removal values showed that the modified activated carbon is a promising adsorbent for heavy metal removal from wastewater.

“…Nano zero-valent iron (nZVI) is another noticeable nanoparticle used for wastewater treatment and heavy metal removal. It removes heavy metal ions by using reactive technologies, which make degradation and transformation of contaminants into harmless products possible [16,18]. In situ use of nZVI mostly starts by injecting it to the wastewater solution.…”

“…It increases the ambient pH and decreases the redox potential of the solution. In addition to the changes applied to the wastewater after injecting the nZVI, the nZVI particles themselves undergo a chemical transformation by coating with natural organic matters in the waste solution [18]. The last kind of nanoparticles are hybrid magnetic nanoparticles.…”

Background: Ferric oxide (hematite, Fe2O3) nanoparticles were developed under laboratory conditions by co-precipitation method for the adsorption of copper from the metal industry wastewaters. The characteristics of the synthesized nanoparticles were assessed using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning electron microscope (FESEM) and energy-dispersive X-ray (EDX) analyses. Results: Batch adsorption experiments were performed by adjusting the pH (3.0, 7.0 and 9.0), the contact time (10 min, 20 min and 30 min), stirring speed (5000 1/sn, 10000 1/sn and 20000 1/sn), and Fe2O3 concentration (2 mg/l, 5 mg/l and 10 mg/l). The magnetic nanoparticle showed an excellent performance in removing copper. Conclusıon: For maximum copper removal (98%), 10 min of the optimum pH contact time and 5 mg/l Fe2O3 concentration are among increasing concentration of copper (5 mg/l, 25 mg/l and 30 mg/l), at a stirring speed of 150 rpm. The recovery yield of Fe2O3nanoparticle was 89% after 2 years.

The manufacture of activated carbon from oil palm frond waste using an ultrasonic wave activator has been successfully carried out. The carbonization process was carried out at a temperature of 250ºC for 90 minutes. Activation with ultrasonic waves (35 Watt, 40 KHz) for 30 minutes was able to increase the iodine number from 330.06 mg/g to 799.14 mg/g and was in accordance with SNI No.06-3730-1995. FTIR spectra show that the activated carbon of oil palm fronds has a functional group –OH at wave number 2900-3200 cm-1, C=C at wavenumber 1500-1600 cm-1, C-O at wavenumber 1200-1250 cm-1. The results of the adsorption test on Rhodamine B dye showed that the activated carbon produced had an optimum absorption capacity of 9.04 mg/g at a concentration of 400 ppm for 90 minutes. Studies show that the adsorption isotherms absorption mechanisms tend to follow the Freundlich equation with a correlation coefficient (R2)= 0.9861.
