“…This e ciency reduction is due to a decrease in the number of available active sites on the surface of the adsorbent and the saturation of these locations on the adsorbent surface. Ine cient removal of phenol in higher concentrations can be related to the reduced rate of mass transfer and subsequent reduction in adsorption capacity [32,38]. Di erences between aloe vera and mesquite as nano-bioadsorbents revealed that the e ciency of phenol removal has greatly increased by mesquite with a steeper slope than aloe vera, whereas both nano-bioadsorbents had the maximum adsorbent capacity at the initial concentration of 32 mgL 1 of phenol.…”

Abstract. This study was performed to measure the potential utilization of agro-waste to generate nanoparticles and evaluate its capability as a low-cost adsorbent for phenol removal. Adsorption studies for phenol removal using aloe vera and mesquite leaves nanoparticles were carried out under various experimental conditions including pH, nanobioadsorbent dosage, phenol concentration, contact time, temperature, and ionic strength in a batch reactor. The adsorption kinetics were applied by pseudo-rst order and pseudosecond order models and isotherm technique by Freundlich and Langmuir isotherms models. The results showed that the rate of phenol adsorption increases in both nano-bioadsorbents with an increase in pH up to 7, adsorbent dosage up to 0.08 gL 1 , phenol initial concentration up to 32 mgL 1 , contact time up to 60 min, and a raise in temperature. The adsorption data followed the Freundlich isotherm model. The kinetic studies indicated that the adsorption of phenol with nano-bioadsorbents was best described by the pseudo-second order kinetics. We found that the nanoparticles prepared from aloe vera and mesquite leaves had a high capability in adsorption of phenol, besides the point that they could be accessed at low cost. These agro-wastes can be used to remove phenol from aqueous environments.

“…So at the high flow rate, the phenol solution left the column before equilibrium occurs. Furthermore, a fixed saturation capacity of bed based on the same driving force gave rise to a shorter time for saturation at a higher flow rate [8,34,35].…”

“…The use of granular activated carbon (GAC) for removing toxic organic chemicals including phenol from wastewater is one of the best commercially proven methods. Although activated carbons exhibit an excellent adsorption capacity for the removal of phenol from wastewater, this method exhibited the difficulty to its regeneration and quite expensive to dispose of [7][8][9][10][11][12].…”

Olive oil extraction generates a large quantity of wastewater which is a strong pollutant due to its high organic load and phytotoxic. However, its content in antibacterial phenolic substances displays to be resistant to biological degradation. The discharge of olive mill wastewater (OMWW) is not allowed through the municipal sewage system and/or in a natural effluent. Unfortunately, the current technologies for the treatment of OMWW are expensive and complicated to be operated in a mill factory where the objective of this study. We have designed and implemented a process that permitted both the treatment of agro-food processing water and the recovering of compounds of market interest. The process was applied in the effluents of olive oil mill factories to recover polyphenols with a possible significant reduction of organic waste. The nanofiltration fraction obtained from a sequential treatment involved coagulation, photocatalysis, ultrafiltration and nanofiltration was performed to separate the most valuable compounds using column adsorption runs. Competitive adsorption and the selectivity were obtained for phenol and hydroxytyrosol onto macro-reticular aromatic polymer (FPX66) and macroporous polystyrene cross-linked with divinylbenzene (MN202), respectively. The investigations were followed by a single component of phenol or tyrosol, binary phenol and tyrosol and ternary components in NF concentrate of OMWW for valuable compounds recovery conducted in a fixed-bed adsorber of resins. During the intermediate stage of the column operation, adsorbed tyrosol molecules were replaced by the incoming phenol molecules due to the lower tyrosol affinity for FPX66 resin and the tyrosol concentration was higher than its feed concentration.

“…The use of macroporous resins to phenolic fraction valorisation involve higher selectivity, easier desorption, lower solvent consumption, absence of chemical residues in the product, better mechanical strength and ability to reuse (Petrotos et al, 2016). Thus, the adsorption process is preferred because it is a low-cost separation technique, applicable for industrial scale processes, with high adsorption capacities, possible recovery of the adsorbed molecules and easy regeneration (Abdelkreem, 2013;Kammerer et al, 2011;Soto et al, 2011). Resins have been applied for the adsorption of phenolic compounds and hydroxytyrosol from olive oil mill wastewater (Agalias et al, 2007;Frascari et al, 2016;Petrotos et al, 2016Petrotos et al, , 2013, hydroxytyrosol and tyrosol from fermentation brine wastewater (Ferrer-Poloniom et al, 2016), spinacetin and patuletin from spinach leaves (Aehle et al, 2004), polyphenols from kiwifruit juice (Gao et al, 2013), limonin and naringin from orange juice (Ribeiro et al, 2002), hesperidin from orange peel (Di Mauro et al, 1999), anthocyanins from roselle (Chang et al, 2012), narirutin from a water-extract of Citrus unshiu peels (Kim et al, 2007), genistein and apigenin from extracts of pigeon pea roots (Liu et al, 2010), anthocyanins and hydroxycinnamates from orange juice (Scordino et al, 2005), chlorogenic acid and apigenin-7-O-glucoside from artichoke wastewaters (Conidi et al, 2015), catechin, epicatechin, epicatechin gallate, epigallocatechin gallate and caffeine from green tea (Jin et al, 2015; MARK 2016), catechins and theaflavins from black tea (Monsanto et al, 2015).…”
