Some agricultural byproducts are useful for solving wastewater pollution problems. These byproducts are of low cost and are effective and ecofriendly. The study aim was to investigate the possibility of using pomegranate peel (PP) and date pit (DP) activated carbon (PPAC and DPAC, respectively) as sorbents to remove Cd(II) and Pb(II) from aqueous solutions. Agricultural wastes of DPs and PPs were subjected to carbonization and chemical activation with H3PO4 (60%) and ZnCl2 and used as adsorbents to remove Cd(II) and Pb(II) from their aqueous solutions. The physical characterizations of PPAC and DPAC, including determination of surface area, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Fourier-transform infrared spectroscopy, were performed. The following factors affected adsorption: solution pH, adsorbent dosage, initial metal ion concentration, and contact time. These factors were studied to identify the optimal adsorption conditions. The results showed that the maximum adsorptions of Cd(II) and Pb(II) were achieved at pH ranging from 6 to 6.5, 90 min contact time, and 0.5 g/L for PPAC and 1 g/L for DPAC dosage. Furthermore, the adsorption efficiencies for both Pb(II) and Cd(II) were higher for PPAC than for DPAC. However, the recorded Qmax values for PPAC were 68.6 and 53.8 mg/g for Pb(II) and Cd(II) and for DPAC were 34.18 and 32.90 mg/g for Pb(II) and Cd(II), respectively. The Langmuir isotherm model fit the adsorption data better than the Freundlich model. Kinetically, the adsorption reaction followed a pseudo-second-order reaction model, with qe ranging from 12.0 to 22.37 mg/g and an R2 value of 0.99.

The main techniques used for organic pollutant removal from water are adsorption, reductive and oxidative processes, phytoremediation, bioremediation, separation by membranes and liquid–liquid extraction. In this review, strengths and weaknesses of the different purification techniques are discussed, with particular attention to the newest results published in the scientific literature. This study highlighted that adsorption is the most frequently used method for water purification, since it can balance high organic pollutants removal efficiency, it has the possibility to treat a large quantity of water in semi-continuous way and has acceptable costs.

Furfural is an organic aromatic compound that has attracted considerable interest as a potential chemical for the production of biochemical and biofuels. However, furfural has proved to possess ecotoxic effect on the environment and to humans, therefore measures are required to prevent these effects. One of the most widely used methods for eliminating furfural is the surface adsorption process.The present study focused on the structure and morphology of the composite nanoparticles, investigated using FTIR, XRD, BET and FE-SEM techniques.Furthermore, the variables of time, solution pH, dosage composite and initial furfural were evaluated. Furfural adsorption was performed by spectrophotometer at a wavelength of 227 nm. The removal efficiency under optimal conditions for furfural (Furfural concentration of 250 mg/L, the composite dose of 4 g/L, the reaction time of 60 min and pH = 7) was 81.46%. In addition, the study of isotherm and adsorption kinetics for furfural showed that the adsorption process follows the Langmuir isotherm and quasi-quadratic kinetics. The qmax of the composite was determined by the Langmuir model of222.22 mg/g. Therefore, the present study exclusively showedthat the activated carbon coated with nZVI nanoparticles used as an effective and environmentally friendly adsorbent for furfural removal from aqueous solutions. Furthermore, this study could possibly have applied for the adsorbtion of other chemical cmpounds such as dyes,metronidazole,aniline.
