“…Olive stones pyrolysed at 500°C (SA of 760 m 2 /g) demonstrated a high capacity for phenolic compounds, 500 mg/g, and sulphonic compounds, 570 mg/g, due to their ability to IIbond on the positive carbon surface [186]. Several other olive industry wastes have undergone physical treatment/activation.…”

Olive stones have been widely used as a renewable energy biowaste source. As they are rich in elemental carbon (40-45 wt%), much research focussed on effectively converting olive stones, as precursors, into activated carbon adsorbents. However, only a few studies have concentrated on summarising the various techniques used to produce activated carbon from olive stone. This article reviews the research undertaken on the production and application of activated carbon as an adsorbent from olive stones for wastewater treatment. Various physical, chemical and physico-chemical treatments to remove heavy metals, organics and dyes are discussed, and the resultant adsorption capacities are reported. In several cases, very high adsorption capacities are recorded. Finally, the future prospects of these materials as adsorbents are discussed, and after further development work, olive stone-derived activated carbons have great potential especially in the area of organic polluted wastewaters.

“…These authors also reported that the influence of temperature (4 °C and 28 °C) on performance was negligible and a full-scale carbon filter unit will be sufficient to remove environmentally relevant nonylphenol concentrations of 10 μg/L. Later, Tsyntsarski et al (2014) demonstrated that the amount of carbon had no significant influence on performance. Yu et al (2009) evaluated the adsorption of nonylphenol on granular activated carbons, with a particular focus to adsorption mechanism.…”

“…Since the 1980s, activated carbons have also been proposed to remove alkylphenols and alkylphenol ethoxylates (Singer and Yen 1980). Abundant data have been published on this topic (Iwasaki et al 2001;Tanghe and Verstraete 2001;Dąbrowski et al 2005;Crini and Badot 2007;Yu et al 2009;Çeçen and Aktaş 2012;Tsyntsarski et al 2014;Katsigiannis et al 2015;Mailler et al 2016;Jeirani et al 2017;Priac et al 2017;Vatankhah et al 2019). Iwasaki et al (2001) reported that alkylphenols had very high adsorbability by microporous activated carbon having high specific surface area (carbon prepared from coconut shell, powder with specific surface area ranging from 500 to 1800 m 2 /g).…”

Since the 2000s, among organic contaminants, alkylphenols and alkylphenol polyethoxylates have been listed as hazardous substances by several national, European and international agencies because they are considered endocrine disruptors. Among the molecules classified as priority substances in terms for monitoring and action, nonylphenols and octylphenols and their polyethoxylated derivatives receive particular attention, especially in developing countries. Effluents from treatments plants are considered to be the largest source of alkylphenols in the environment. Although legislation concerning their use has become increasingly strict, these substances are still found in the environment, especially in water resources.The existing water and wastewater treatment plants have not been designated for these emerging contaminants. Conventional treatments such as biodegradation, sand filtration, carbon adsorption and/or chemical oxidation in place are not effective in their elimination removal. No appropriate methods have been developed to deal them at the urban or industrial scale. Thus, alkylphenols have become a relevant research topic for scientists interested in water engineering issues related to

“…Recently the thermo-chemical conversion of plastic by-products has become popular due to their availability and potential to produce energy as well as activated carbon with very good properties. Our earlier investigations [14,15], which are focused on the synthesis of porous carbons, show that the chemical composition of the precursor strongly influences the structure and properties of the obtained adsorbent. For instance, the carbonizate-before activation-obtained from pyrolysis of a specific raw material containing dominantly aromatic compounds (such as biomass derived tar), is characterized by a dense structure and weak reactivity towards steam activation.…”

Nanoporous carbon is synthesized on the base of phenol-formaldehyde resin and polyolefin wax, a by-product from industrial production of polyethylene at low pressure. The adsrption of phenol derivates from aqueous solutions on obtained carbon material was studied. The adsorption capacity of the carbon is related to the surface area and composition of the synthesized material, as well as to the nature of the adsorbent. The obtained adsorbent is characterized by high surface area and porosity, and it demonstrates high adsorption capacity towards aromatic compounds. All studied phenolic compounds show high affinity towards carbon, confirming that the retention mechanism occurs via non-specific interactions between the electronic density of the adsorbent and molecules of aromatic pollutants. Electrostatic interactions may also appear depending on pH of the solution pH and charge distribution of the carbons; and these effects has a strong influence on the final performance of the carbon.
