“…56 Furthermore, large amount of H + in low pH solution would generate great competitive effect towards metal ions, hindering the adsorption process. 27 In agreement to these effects a low adsorption capacity is obtained for all studied metal ions for a pH ranging from 1 to 3 (Fig. 6(a) and (b)).…”

“…Literatures have reported the application of BSG as a biosorbent for metal ions, such as Mn 2+ , Zn 2+ , Ni 2+ , Cd 2+ , Cu 2+ and Pb 2+ . [25][26][27][28] Recently, activated hydrochar produced from BSG is reported for the adsorption of acetaminophen. 29 Nevertheless, it is worth to notice that the activated hydrochar was obtained at 220 C for 16 h with a chemical activation process using KOH and high temperature (800 C).…”

Adsorption to date is the most effective and utilized technology globally to remove several pollutants in wastewater. In this approach, many adsorbents have been synthesized, tested and used for the elimination and separation of the contaminants such as radionuclides, heavy metals, dyes and pharmaceutical compounds both at lab and industrial scale. However, there are many challenges to adsorption processes such as reducing the high cost, through means of separation of suspending adsorbents to be used again, as well as the ease to synthesize. Two methods that have shown promising results and gained significant interest is that of magnetic nanomaterials and biosorbents due to their effective, safe, eco-friendly, low cost and low-energy intensive material properties. Magnetic nanomaterials act as efficient adsorbents due to their ease of removal of contaminants from wastewater using an applied magnetic field but also their advantageous surface charge and redox activity characteristics. On the other hand, biosorbents have a synergistic effect with their efficient adsorption capacity to remove contaminants, high abundance and participation in waste minimization, helping alleviate ecological and environmental problems. This review highlights, discusses and reports on the state-of-the-art of these two promising routes to adsorption and provides indications as to what are the optimum materials for utilization and insight into their efficiency, reusability and practicality for the removal of pollutants from wastewater streams. Some of the main material focuses are zero-valent iron, iron oxides, spinel ferrites, natural and waste-based biosorbents.

“…Bioadsorption of pollutants from cellulosic biomass residues has attracted attention because it not only allows the removal of heavy metals in industrial effluents, but also treats agricultural waste that is produced today in huge amounts and does not have a specific use [12]. In this sense, they have been studied as adsorbents including rice husk [13,14], sawdust [15,16], fruit peels [17,18] and others [19,20].…”

This article shows how pine sawdust residues can be used to adsorb nickel ions from synthetic solutions and then to produce porous bricks for civil construction using a mixture of natural clay and biomass containing the adsorbed metals. The adsorption tests were performed by mixing NiCl2 solutions with pine sawdust during a fixed stirring period of 24 h. The set was filtered and the filtrate was analysed. Highest efficiency adsorbate/adsorbent ratio was 50 mL of 1 M NiCl2 solution and 20 g L− 1 of pine sawdust. This was the contaminated biomass sample used in the manufacture of the bricks. This paper analyses the properties of the bricks achieved and compares them with bricks without added biomass, porous bricks containing zinc and commercial bricks. The obtained values of bulk density, apparent specific weight, apparent porosity, water absorption, apparent volume, weight loss on ignition, compressive strength, flexural modulus of rupture and efficiency retention of metal in the brick, demonstrate that the ceramic pieces obtained are optimal for construction.
