Phosphorylated cellulose paper as highly efficient adsorbent for cadmium heavy metal ion removal in aqueous solutions

Abstract

In search for more effective and eco-friendly adsorbent materials, this study comprehensively investigated Cd2+ adsorption onto phosphorylated cellulose paper (PCP).

Hybrid carbonaceous adsorbents based on clay and cellulose for cadmium recovery from aqueous solution

“…51 The surface charge of an adsorbent material generally has the strongest effect on its effectiveness. 52 Therefore, the zeta potential was measured under various pH levels in order to determine the surface charge properties of Gh and ca-GH, as shown in Fig. 4(b).…”

“…Due to their affordability, effectiveness and biodegradability, lignin, cellulose, chitin and alginate-based adsorbents have been employed widely, as it's the case in those research. [26][27][28][29][30] Those biopolymers have a variety of functional groups which improve the effectiveness of removing heavy metals from water samples. [31][32][33][34][35] Cellulose can be found in wood and cotton; however, many other resources have been investigated to resolve environmental concerns.…”

Probing the evolution in catalytic graphitization of biomass-based materials for enduring energetic applications

“…[12][13][14] Biomass is a renewable resource derived from various organic materials, including plant components such as lignin and cellulose. [15][16][17] This renewable character contrasts sharply with traditional carbon precursors such as coal, methane, and liqueed petroleum gas, which are nite and non-renewable. 18,19 Moreover, biomass is abundant on a global scale, making it easily accessible and cost-effective.…”

Adsorption Properties of Natural Zeolite Supported by Chitosan on Cd(II) in Micropolluted Irrigation Water

“…Many researchers have studied the use of natural or synthetic zeolites, industrial waste materials, agricultural byproducts, clay minerals, and other materials as adsorbents. Zeolites are a group of hydrated aluminosilicate minerals with a unique crystal structure containing numerous cavities and channels internally.…”

“…24,25 Therefore, the development of highly efficient, low-cost, and environmentally friendly adsorbents has become an important direction of research for scholars both domestically and internationally. Many researchers have studied the use of natural or synthetic zeolites, industrial waste materials, 26 agricultural byproducts, 27 clay minerals, and other materials as adsorbents. Zeolites are a group of hydrated aluminosilicate minerals with a unique crystal structure containing numerous cavities and channels internally.…”
