“…Malachite green (MG) is a common cationic dye and easily soluble in water. MG can kill fungi, bacteria and parasites in water and dye materials such as textiles, wool, and paper products [4]. Therefore, it is widely used in the fishery and textile industry.…”

In this study, banana biochar (BB) and cassava biochar (CB) were roasted in a tube furnace at 400℃ for 2 h, and their adsorption effects on malachite green (MG) were studied. The removal of MG with respect to the solution concentration and reaction time was also investigated. The results show that the optimal amount of biochar is 2 g/L. Studies of the adsorption kinetics and adsorption isotherms show that the pseudo-second-order kinetics can most accurately reflect the adsorption process. Freundlich model fits the experimental data well. The theoretical saturated adsorption capacities of BB and CB are 1,092.80 mg/g and 261.42 mg/g, respectively. SEM-EDS, TGA, BET, FTIR, XRD, element analysis and other characterization techniques were used to explore the adsorption mechanism. Based on the characterization results, it is speculated that the adsorption of BB and CB for MG mainly includes chemical adsorption and physical adsorption.

“…In particular, chemically modified polymeric materials are considered to be very effective adsorbents for removing dye molecules from aqueous solutions without leaving any adsorbent residue (Pan et al 2009). Various kinds of polymeric materials such as polyaniline (Kanwal et al 2018;Wang et al 2019a, b), chitosan (Vilela et al 2019), polyvinyl alcohol (Sanchez et al 2019;Dai et al 2018), polystyrene (Al-Sabagh et al 2018Wen et al 2015), polyacrylamide (Zhang et al 2018), polyurethane (Lefebvre et al 2018;Kumari et al 2016) and cellulose (Tong et al 2018;Varghese et al 2019) are currently being researched for the use in the treatment waste waters. However, these polymers are used as a matrix of a composite in which the adsorption is realized by the additives of the composite such as bentonite, montmorillonite, silica, zirconium oxide, alumina, iron oxide, etc.…”

Herein a novel polymeric adsorbent composite material was introduced for the adsorption of methylene blue from aqueous solutions for the purpose of water treatment. Adsorption process was examined by using Langmuir and Freundlich isotherm models together with pseudo-first and second order kinetic analysis. It was found that characteristic of the adsorption process was well described by Langmuir isotherm following pseudo-first order kinetic route. The maximum monolayer adsorption capacity was determined as 49.04 mg g −1 . In light of thermodynamic parameters of the adsorption and removal of MB from the composite in acidic solution suggested that the process was based on ion-exchange mechanism. Negative values of Gibbs free energies changing from − 5.41 to − 15.99 kJ mol −1 with increasing temperature demonstrated that adsorption process occurs spontaneously. Heat of adsorption and entropy values were found as 58.30 kJ mol −1 and 0.23 kJ mol K −1 , respectively. Therefore, adsorption process was endothermic in nature without noticeable disorder. The material consisting of functionalized poly(methyl methactrylate) in the polyvinylidene fluoride-hexafluoropolypropylene matrix is considered to be a potential adsorbent material for the treatment of polluted waters.

“…Forefront research lines are focused on the production of new low-cost adsorbing materials. For example, different activated charcoals from coconut husks or olive stones, among other residues [10][11][12][13]. Moreover, agro-industrial leftovers without any treatment such as rice husk, orange peel and cork slices have been also considered as low-cost adsorbents [14][15][16].…”

This study demonstrates the viability of an orange peel-based adsorbent as sustainable alternative for the elimination of the disperse dye C.I. Disperse Blue 56 present in waste waters of the dyeing industry of textiles. The effectiveness of the adsorbent is evaluated at different pH values and the adsorption capacity is determined by systematically comparing orange peel and the final adsorbent chemically treated. Results reveal an spontaneous coagulation-flocculation phenomenon of the dispersed dye at low pH values which represents a sustainable way for the recovery and possible re-use of the dye, together with the industrial valorisation of a wasting product as is orange peel.
