“…There are many well-known processes regarding the treatments of contaminated wastewaters like membrane filtration, 1-4 chemical precipitation, [5][6][7] electrocoagulation, [8][9][10][11][12] reverse osmosis, [13][14][15] adsorbtion, [16][17][18][19][20][21][22][23][24] ion exchange, [25][26][27] etc., all of them with their inherent advantages and disadvantages. At the same time, most of them are not suitable for developing countries due to huge cost investment in terms of use of chemicals, infrastructure, and operation.…”

Adsorption of heavy metals (Pb, Zn, and Cu) on a new bioadsorbent based on starch reinforced with modified cellulose with toluene‐diisocyanate has been studied using batch‐adsorption technology. The study was carried out in order to find if this bio material, designed for seedling pots manufacture, is able to act like a barrier between soil pollutants and plants. The influence of contact time, pH, adsorbent dose, and salt concentrations was also evaluated. The obtained data were examined using the Langmuir and Freundlich adsorption models. Optimal results were obtained at pH 5.0, temperature of 25°C, contact time of 120 minutes, and an adsorbent dose of 4 mg/mL. Experimental data along with computed Langmuir parameters show that the adsorption process is favorable, and the maximum adsorption capacity of the adsorbent for lead, zinc, and copper was 66.66, 58.82, and 47.61 mg/g, respectively.

In the current work, nanocomposites of Mg−Al and Mg−Fe layered double hydroxides (LDHs) anchored on silica foam (SF), denoted as MAL/SF and MFL/SF, respectively, were fabricated using a two‐step route. The obtained LDHs/SF nanocomposites were characterized by XRD, TEM, SEM, EDS, elemental mapping, and N2 adsorption‐desorption techniques. Sorption of the heavy‐metal Pb(II) and Cr(VI) on the LDHs/SF was determined at 25 °C and pH 5.5 using a batch technique. In comparison with bulk Mg−Al and Mg−Fe LDHs, the LDHs in the MAL/SF and MFL/SF exhibit significantly enhanced sorption capacities. In addition, the LDHs/SF nanocomposites show a good recyclability for removing heavy metals. The construction of LDHs/SF nanocomposites is an effective strategy for improving the sorption capacity of LDHs, and the nanocomposites are potential sorbents for wastewater treatment.

“…In catalysis, the objectives are to obtain a catalyst with good catalytic activity, selectivity, stability, recovery and recycle properties. [25,26] More importantly, in recent times, the drive towards green process has also impacted on obtaining techno-economical processes. Hence, newer environmentally friendly catalytic systems are gaining grounds in modern industrial process.…”

Ion exchange resins (IER) possess a catalytically flexible structure which enables them to be easily applied for renewable energy production and environmentally friendly reactions. More specifically, they can be used as catalyst or catalyst support in other industrialized processes such as; esterification, transesterification and hydrogenation reactions. Several works on esterification, transesterification and hydrogenation reactions are in literature. This study reviews some of these works which includes the utilization of IER in esterification, trans-esterification and hydrogenation reactions. Recent reports show that IER are conventionally used as catalyst in esterification and transesterification reactions. For hydrogenation reactions, IER have been utilized as support for metallic catalyst, raising questions on their inability to be applied as catalyst. Hence, this study has itemized these various reactions, detailing their applications which are highly industrialized reaction processes.
