“…The maximum adsorption capacities are 38.39 mg/g and 32.68 mg/ g for Cu(II) and Ni(II), respectively, which are better than that of adsorbents based on chitosan reported in the literatures (Table 3). [31][32][33][34][35][36][37] The K L value of Cu(II) ion is higher than that of Ni (II) ion, which indicates that Cu(II) ion has the higher binding affinity with AO-PAN-g-CS/Fe 3 O 4, thus the adsorption capacity of AO-PAN-g-CS/Fe 3 O 4 for Cu(II) ion is larger.…”

In this study, a novel amidoxime‐based magnetic adsorbent (AO‐PAN‐g‐Chitosan/Fe3O4) was prepared by grafting acrylonitrile onto the surface of chitosan (CS) and magnetic Fe3O4 composite, followed by amidoximation. The magnetic adsorbents were characterized by infrared spectroscopy (FT‐IR) and X‐ray diffraction (XRD). The adsorption properties of the magnetic adsorbents for heavy metal ions in aqueous solutions were investigated under different conditions, including pH, contact time, and initial concentration of heavy metal ions. Under optimum conditions, the maximum Cu(II) and Ni(II) ion adsorption efficiencies were determined to be 38.39 mg/g and 32.68 mg/g by AO‐PAN‐g‐Chitosan/Fe3O4, respectively. Significantly, the Fe3O4/AO‐PAN‐g‐CS can be reproduced in a simple way and reused after five adsorption‐desorption cycles without any significant loss in the adsorption capacity.

“…where q e (mg/g) is the value of the adsorption capacity at equilibrium and q t (mg/g) represents the value of q at time t (min), k 1 (1/min) and k 2 (g/mg.min) shows the rate constants of the pseudo first-order and the pseudo-second-order adsorption procedures, respectively [57][58][59][60][61][62][63][64]. In this work, the kinetics of the adsorption of Acid Blue 25 dye onto CLP as adsorbent was tested by taking 50 mL of the dye solution with a concentration 10 mg/L and the solution was monitored according to the prior method (solution pH 3-4, adsorbent dosage 100 mg, for the kinetic experiments at 25 °C).…”

In this study, the Chicory leaf powder (CLP) was used as a native adsorbent to eliminate the Acid Blue 25 dye from aqueous media. The prepared native adsorbent was characterized by several techniques including the X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform spectroscopy (FTIR), Brunauer-Emmet-Teller essay (BET), and particle size analyzer (PSA). A collection of experiments was performed to distinguish the optimal conditions and to probe the effects of the different parameters such as initial concentration, contact time, adsorbent dosage, pH of solution, and temperature on the sorbent capacity. The attained optimal conditions for removal the Acid Blue 25 dye were pH = 3-4, contact time 50 min, dosage 0.1 g, and initial concentrations 10 (mg/L) at 30 °C. The adsorption data revealed that the adsorption procedure has more match with the Langmuir isotherm than others. The kinetic data were better fitted with the pseudo-second-order pattern with a trusty correlation coefficient. Finally, the thermodynamic parameters illustrated that the adsorption process is exothermal and spontaneous. Based on magnitude of the standard enthalpy change related to the studied adsorption, we may derive that the considered adsorption is physical adsorption.

“…Crosslinked chitosan/Waste Active Sludge Char (WASC) beads were developed as a novel composite adsorbent for the removal of Cu(II) ions from aqueous solution (Dandil et al, 2019). A study conducted using Cu(II) adsorbed from aqueous solutions quickly and efficiently by the xanthate Fe3O4-CS-GO complex, suggested that xanthate Fe3O4-CS-GO may be an ideal candidate for removing Cu(II) from wastewater (Liu et al, 2016).…”

The rapid growth of the industry is giving positive effects for humans by providing daily needs and supporting economic development. However, the industrial process also releases pollution to the environment, which can cause water scarcity, biodiversity loss, and climate change. Removing these pollutants from various industrial wastes is a requirement for ensuring proper water quality for human consumption, agricultural use, and environmental safety. This work aims to explain the use of natural resources as a source of valuable compounds that can be used in wastewater treatment, particularly in Indonesia, by adopting a literature study method reviewing both national and international references. Chitosan is an effective bio-absorbent pollutant because of its high level of deacetylation and free amino groups, making it polycationic which is capable of being bound to metals, proteins, and dyes. Chitosan membranes can be applied only with chitosan material and composites: chitosan-Polyethylene Glycol (PEG), chitosan-Poly Vinyl Alcohol, chitosan-biosilica, chitosan-PVA-silica, chitosan-alginate, chitosan-cellulose, and chitosan-silica. Chitosan has the ability as a coagulant and reducing water turbidity. Chitosan can absorb metal ion (Cr (VI), Cs+, Pb(II), Fe, Cu(II)), dyes (anthraquinone dyes, brilliant blue, yellow dye, methylene blue, disperse orange, disperse blue, rhodamine B), drug residue, and hazardous materials, and can be used as raw material or in a film form. Since there is a high abundance of chitosan raw material in Indonesia, it is supposed to be able to support the application of chitosan as a natural purifying agent considering its high ability to absorb heavy metal and some dangerous materials.
