“…It is prepared by chemical or steam activation of char that can be made of different materials such as fossils or biomass. Nowadays, due to the demand for affordable adsorbents, attempts are made to replace commercially available ACs by biomass waste-produced ACs, e.g., waste tea [23, 24], rice husk [25], and oak wood (Liu et al, [26]). These ACs are not only economical but also proven to be environmentally sustainable.…”

Recent trends in adsorption of hazardous organic pollutants including Polyaromatic Hydrocarbons (PAHs), Chemical Oxygen Demand (COD), Pharmaceuticals, and Chemical Dyes in wastewater using carbonaceous materials such as activated carbon (AC) and biochar (BC) have been discussed in this paper. Utilization of biomass waste in the preparation of AC and BC has gained a lot of attention recently. This review outlines the techniques used for preparation, modification, characterization, and application of the above-mentioned materials in batch studies. The approaches towards understanding the adsorption mechanisms have also been discussed. It is observed that in the majority of the studies, high removal efficiencies were reported using biowaste adsorbents. Regarding the full potential of adsorption, varying values were obtained that are strongly influenced by the adsorbent preparation technique and adsorption method. In addition, most of the studies were concentrated on the kinetic, isotherm equilibrium, and thermodynamic aspects of adsorption, suggesting the dominant isotherm and kinetic models as Langmuir or Freundlich and pseudo-second-order models. Due to development in biosorbents, adsorption has been found to be increasingly economical. However, application of these adsorbents at commercial scale has not been adequately investigated and needs to be studied. Most of the studies have been conducted on synthetic solutions that do not completely represent the discharged effluents. This also needs attention in future studies.

Heavy metal removal from the water was studied by using fish bones produced in the trout farm of Atatürk University Faculty of Fisheries. Fish bones used as adsorbent were obtained from rainbow type trout (Oncorhynchus Mykiss). Trout bone was used in its natural form. According to the experimental results that 1 g of Rainbow trout bones (RTB) can adsorb 188.16 mg of lead (qmax). Langmuir and Freundlich isotherm models were found more favourable for the adsorption of Pb (II) on to RTB than Temkin with the correlation coefficients of 0.999, 0.999 and 0.857, respectively. The optimum working parameter values for Pb (II) adsorption using RTB were found to be 30oC, 3 g/L, 200 rpm and 10 mg/L for temperature, adsorbent concentration, stirring speed and initial Pb (II) concentration, respectively. In the kinetic phase of the study, pseudo-second-order kinetic model gives more favourable results (R2mean= 0.997) than pseudo-second-order (R2mean= 0.971). Fish bones were characterized by some instrumental analyses such as SEM, EDS, FTIR and zeta potential measurements. In the regeneration phase of the study, maximum desorption efficiency was 95.86% at pH 1.5.
