In recent decades, treatment of polluted water has shifted towards the enhancement of environmentally friendly adsorbents. In this regard, a biosorbent originated from pineapple peel cellulose was synthesized and used for the adsorption of Cu2+ and Zn2+. The magnetic (3-aminopropyl)triethoxysilane was designated to immobilize modified cellulose and ethylenediaminetetraacetic acid. The biosorbent was characterized by FE-SEM, TEM, EDX, XRD, FT-IR, BET, VSM and TGA techniques. The influence of pH, temperature and biosorbent dosage on the cation removal was investigated by Central Composite Design. The maximum uptake% was 93.18 and 96.30% for Cu2+ and Zn2+, respectively. Coordination and electrostatic attraction were proposed as the main reasons for the removal of heavy metal cations. The adsorption of Zn2+ was ultrafast and completed within 40 s and it took 420 s for totally removal of Cu2+. External surface biosorption, the intra-particle diffusion and the diffusion through the smaller pores and slits, in sequence, were the dominant steps in the adsorption of each cation. Modified pseudo-n-order and modified Langmuir-Freundlich were the best models to describe kinetics and equilibrium results. The maximum adsorption capacity of biosorbent for Zn2+ was higher than one for Cu2+ (153.9 versus 149.4 mg·g-1). The regenerating of biosorbent was successfully accomplished for five cycles using a solution of EDTA in the presence of ultrasonic waves.

“…Development of an environmentally friendly adsorption process has extensively attracted the researchers' attention. Biosorption, a process in which the agricultural wastes, bacteria, algae and fungi are used as the biosorbents (Vanhoudt et al 2018;Salih et al 2020), has gotten one of the treatment methods for water laden with heavy metal ions (Sheikh et al 2021;Chun et al 2022). This technique is well-known for its flexibility, low initial cost, design simplicity and ease of operation (Hussain and Kadeppagari 2022).…”

In recent decades, remediation of polluted water has shifted towards the enhancement of environmentally friendly adsorbents with robust stability. In this regard, a biosorbent was designed and synthesized by anchoring carboxylated pineapple peel cellulose and ethylenediaminetetraacetic acid onto amino-silane modified Fe3O4 nanoparticles. A vast number of carboxyl and amino active groups in the structure of biosorbent led to the efficient adsorption of Cu2+ and Zn2+ from polluted water. The biosorbent was characterized by FE-SEM, TEM, EDX, XRD, FT-IR, BET, VSM and TGA techniques. The influence of pH, temperature and biosorbent dosage on the cation removal was investigated by Central Composite Design. The maximum uptake% was 93.18 and 96.30% for Cu2+ and Zn2+, respectively. Coordination and electrostatic attraction were proposed as the main reasons for the removal of heavy metal cations. Astonishingly, the adsorption of Zn2+ was ultrafast and completed within 40 s and it took 420 s for removal of Cu2+. External surface biosorption, the intra-particle diffusion and the diffusion through the smaller pores and slits, in sequence, were the dominant steps in the adsorption of each cation. Modified pseudo-n-order and modified Langmuir-Freundlich were the best models to describe kinetics and equilibrium results. The maximum adsorption capacity of biosorbent for Zn2+ was higher than one for Cu2+ (153.9 versus 149.4 mg·g-1). Besides, the regenerating of biosorbent was successfully accomplished for five cycles using a solution of EDTA in the presence of ultrasonic waves.

“…Among these applications, chitosan has received great interest as adsorbents for wastewater treatment [ 18 , 19 , 20 , 21 ]. On the other hand, in the recent literature, some papers deal with the combined use of both diatomite and chitosan to produce adsorbents for environmental pollutant removal, with the aim to evaluate their synergistic adsorption properties [ 22 , 23 , 24 , 25 , 26 , 27 ]. Herein, a chitosan-modified diatomite was synthesized with the aim to produce a novel, broad spectrum hybrid adsorbent.…”

Fabrication of Green Diatomite/Chitosan-Based Hybrid Foams with Dye Sorption Capacity

The latest tendency of the scientific community regards the development of different classes of green materials able to solve pollution problems caused by industrial and human activity. In this paper, chitosan and diatomite were used to produce a broad-spectrum hybrid adsorbent, either in powder or in monolithic form for environmental pollutant removal. Diatomite–chitosan-based powders and porous diatomite–chitosan hybrids were prepared and characterized by chemical-physical, thermal and morphological analysis. Moreover, their adsorbent capacity towards anionic dye (Indigo Carmine) was also evaluated. Obtained data showed that chitosan improves the adsorption capacity of both systems, increasing the uptake of dye in both diatomite–chitosan systems.
