“…Although technologies based on osmosis, oxidation and membrane separation can be effective, operational costs are sometimes high and implementation of these methods are energy‐intensive due to high conversion required and an exhibition of residual activity which are potential risks 20. Adsorption is a simple and cost‐effective method for removing toxins from water, based on the methods used 21, 22. Sorbent materials reported for CBZ removal includes SBA‐15 7, multi‐walled CNTs, activated carbon (AC) 23, biochar 24, nano‐adsorbents 10, and graphene 25.…”

Carbamazepine (CBZ) is a pharmaceutical compound used in medical practice. Due to the ecotoxicological risk of its presence in the aqueous environment, researchers have been investigating its removal by adsorption technique. The aim of this study is to review the works done on the removal of CBZ from water by adsorption. Carbon‐based materials were the best types of adsorbent for CBZ uptake (> 200 mg g−1). Molecularly imprinted polymer (MIP) and carbon nanotubes (CNTs) showed especially good adsorption capacities. The key mechanisms of CBZ adsorption were π‐π interaction, electrostatic interactions, hydrogen‐bonding and hydrophobic interactions. Classical equilibrium isotherm models like Langmuir and Freundlich were always best‐fits and kinetics modelling was best‐fit to the pseudo‐second order model. The thermodynamics modelling of CBZ adsorption showed it was spontaneous and endothermic for most adsorbents. Methanol and acetone were especially effective for the desorption of CBZ from adsorbents and can achieve > 90 % removal even after 4–5 cycles. CBZ competes favorably in adsorption systems with other pharmaceutical species due to the advantages of the hydrophobic effect and molecular size.

“…Batch adsorption was chosen because of availability, facility of operation and reliability, other methods such as oxidation and flocculation produce mud, and membrane separation requires high pressures [27]. The following adsorption experiments are based on the methodology of previous studies on the adsorption of MB using biosorbents [14,15,18,28,29]. Like these other studies, the effects of dosage, solution pH, residence time, solution temperature, initial dye concentration, particle size and agitation were investigated.…”

Biosorbents are an alternative pollutant adsorbent, usually sourced from waste biomass and requiring little to no treatment. This makes them cheaper than conventional adsorbents. In this paper, green pea (Pisum sativum) haulm was used as a biosorbent for the adsorption of methylene blue dye. The potential application of pea haulm as a biosorbent has not been investigated before. Characterisation using scanning electron microscopy, infrared spectroscopy and thermal gravitational analysis showed the surface to be coarse, detected functional groups important for adsorption and identified the composition of key biomass components. The effects of particle size, contact time, agitation, dosage, solution pH, temperature and initial dye concentration on the removal of MB by pea haulm were investigated. Using the data from these studies, the best fitting kinetic and isotherm models were found and the thermodynamic properties were identified. The maximum theoretical adsorption capacity was 167 mg/g, which was relatively high compared to other recent biosorbent studies. The pseudo-second-order adsorption kinetic and Freundlich adsorption isotherm models were the best fitting models. The biosorption process was exothermic and spontaneous at low temperatures. It was concluded that pea haulm was an effective adsorbent of methylene blue and could perhaps find application in wastewater treatment.

Water pollution has generated the need to develop technologies to remove industrial pollutants. Adsorption has been recognized as one of the most effective techniques for effluent remediation. In this study, parts (stem and leaves) of a problematic aquatic weed, the water hyacinth (Eichhornia crassipes), were separated to produce a bioadsorbent. The objective was to evaluate the adsorption of a cationic dye, methylene blue (MB), in an aqueous solution of the biomass from different parts of the water hyacinth (Eichhornia crassipes) plants. The materials were characterized through techniques of infrared spectroscopy, scanning electron microscopy, X-ray diffractometry, and thermogravimetric analysis, before and after the material adsorption. Water hyacinth biomasses presented adsorption capacity above 89%, and the kinetics was faster for stem biomass. The kinetic study found that the adsorption process is better described by the pseudo-second-order model, and the adjustments of the isotherm experimental data indicated that both materials are favorable for adsorption. Therefore, water hyacinth bioadsorbent represents a renewable resource with potential for effluent treatment.
