With the increasing need for bio‐based materials developed by environmentally friendly procedures, this work shows a green method to develop shape‐controlled structures from cellulose dissolving pulp coated by chitosan. This material was then tested to adsorb a common and widespread pollutant, 2,4‐dichlorophenol under different pH conditions (5.5 and 9). Herein it was noticed that the adsorption only occurred in acidic pH (5.5) where electrostatic interaction drove the adsorption, demonstrating the potential to tune the response under desired conditions only. The adsorption was successful in the hydrogel structure with an adsorption capacity of 905 ± 71 mg/g from a solution with 16.6 ppm; furthermore, adsorption was also possible with dried hydrogel structures, presenting a maximum of adsorption of 646 ± 50 mg/g in a similar 16.6 ppm solution. Finally, adsorbent regeneration was successfully tested for both, dry (rewetted) and never‐dried states, showing improved adsorption after regeneration in the case of the never dried hydrogel structures.

“…There are various types of carbon-based materials that can be applied as support materials in improving the structure of LDH, namely graphite, charcoal, chitosan, and biochar [18][19][20][21]. Biochar (BC) is a material produced from the decomposition of organic matter which has advantages including being friendly to the environment, easy to manufacture at low cost, abundant availability of raw materials, and has a porous structure which is very helpful in the adsorption process [22,23].…”

All activities require drinking water. The existence of waste makes water unfit for consumption. Phenol waste is one example of waste that is often found. The toxic and corrosive nature of phenol is very dangerous for life, so its presence must be considered. The adsorption process was carried out using NiAl and ZnAl layered double hydroxides composites with biochar to eliminate the presence of phenol waste The adsorption process was carried out using NiAl and ZnAl layered double hydroxydes materials which were composited with biochar to eliminate the presence of phenol waste. NiAl-Biochar and ZnAl-Biochar composites were successfully prepared, as determined by XRD, FTIR, SEM, and BET analyses. NiAl layered double hydroxide surface area grew from 92.683 to 438.942 m2/g while ZnAl layered double hydroxide surface area increased from 9.621 to 58.461 m2/g. pHpzc of material is between 5.1 and 9.4. Optimal pH of NiAl and ZnAl layered double hydroxide is 3, optimum pH of NiAl-Biochar and ZnAl-Biochar is 5, and optimum pH of Biochar is 7. All kinetic and isotherm models for all materials were pseudo-second-order and Freundlich, respectively. NiAl-Biochar and ZnAl-Biochar have maximal adsorption capacities of 74.62 mg/g and 52.91 mg/g, respectively. The material's reusability indicates that NiAl-Biochar has superior qualities and may be reused for up to five cycles, followed by ZnAl-Biochar, NiAl layered double hydroxide, ZnAl layered double hydroxide, and Biochar.
