“…This was associated to low interaction of the binding sites of the sludge with phenol molecules. Arslan and Dursun [ 97 ] have studied the adsorption of phenol using dried sludge and found that loading capacity increased by increasing the temperature and pH and the maximum adsorption capacity achieved was 42.7 mg/g at pH 8 and a temperature of 40 °C ( Table 4 ).…”

Due to their industrial relevance, phenolic compounds (PC) are amongst the most common organic pollutants found in many industrial wastewater effluents. The potential detrimental health and environmental impacts of PC necessitate their removal from wastewater to meet regulatory discharge standards to ensure meeting sustainable development goals. In recent decades, one of the promising, cost-effective and environmentally benign techniques for removal of PC from water streams has been adsorption onto sewage sludge (SS)-based activated carbon (SBAC). This is attributed to the excellent adsorptive characteristics of SBAC and also because the approach serves as a strategy for sustainable management of huge quantities of different types of SS that are in continual production globally. This paper reviews conversion of SS into activated carbons and their utilization for the removal of PC from water streams. Wide ranges of topics which include SBAC production processes, physicochemical characteristics of SBAC, factors affecting PC adsorption onto SBAC and their uptake mechanisms as well as the regeneration potential of spent SBAC are covered. Although chemical activation techniques produce better SBAC, yet more research work is needed to harness advances in material science to improve the functional groups and textural properties of SBAC as well as the low performance of physical activation methods. Studies focusing on PC adsorptive performance on SBAC using continuous mode (that are more relevant for industrial applications) in both single and multi-pollutant aqueous systems to cover wide range of PC are needed. Also, the potentials of different techniques for regeneration of spent SBAC used for adsorption of PC need to be assessed in relation to overall economic evaluation within realm of environmental sustainability using life cycle assessment.

“…9 Among them, adsorption is by far the most efficient, economical, and versatile method, especially if combined with appropriate regeneration steps, due to the ability of the adsorption process to completely eradicate the pollutants from the wastewater without leaving behind any toxic byproducts. Various materials have been used as adsorbents for the removal of phenol from aqueous solutions, including activated carbon, 10,11 biosorbents (such as chitosan 12 and dried activated sludge 13 ), polymeric adsorbents, 14 y ash, 15 zeolite, 16 soil, 17 coal, 18 red mud, 19 and sewage sludge. 20 Although activated carbons, the most commonly used adsorbent for phenol removal, exhibit satisfactory performance for the removal of phenol from wastewater, the main concerns related to these adsorbents are the high regeneration cost, the generation of carbon nes, and the poor selectivity for recovering specic organic chemicals.…”

“…Phenol is organic synthetic raw material, which is widely used in the manufacture of plasticizers, pharmaceuticals, dyes, antioxidants and so on [1]. However, it is classified as hazardous pollutants, since it is toxic to microorganisms, animals and human beings even at a low concentration [2].The lowest concentration of phenol that causes harm to humans is given as 3.5 mg•L-1 by the U.S. Environmental Protection Agency (EPA).…”

The objective of this paper is to investigate the feasibility of phenol adsorption from aqueous solution by Pinus massoniana biochar. Adsorption conditions, including contact time, initial phenol concentration, adsorbent dosage, strength of salt ions and pH, have been investigated by batch experiments. Equilibrium can be reached in 24 h for phenol from 50 to 250 mg• L-1. The optimum pH value for this kind of biochar is 5.0. The amount of phenol adsorbed per unit decreases with the increase in adsorbent dosage. The existence of salt ions makes negligible influence on the equilibrium adsorption capacity. The experimental data is analyzed by the Freundlich and Langmuir isotherm models. Equilibrium data fits well to the Freundlich model. Adsorption kinetics models are deduced and the pseudo-second-order kinetic model provides a good correlation for the adsorbent process. The results show that the Pinus massoniana biochar can be utilized as an effective adsorption material for the removal of phenol from aqueous solution.
