Elimination performance of methylene blue, methyl violet, and Nile blue from aqueous media using AC/CoFe2O4 as a recyclable magnetic composite

Magnetic methacrylated gelatin-g-polyelectrolyte for methylene blue sorption

“…[9][10][11][12] Among all these methods, adsorption is probably the most common method since it is a simple, efficient, ecofriendly, and low-cost technique. [13][14][15] Hydrogels are three-dimensional cross-linked linear or branched hydrophilic polymers with the ability to retain large volumes of water without being dissolved. 16 Hydrogels based on biopolymers such as starch, chitosan, gelatin, agar, pectin, cellulose, and sodium alginate have received special attention due to their low cost, biodegradability, non-toxic nature, and ease of modication.…”

An effective magnetic nanoadsorbent based on a carbonaceous/spinel ferrite nanocomposite for the removal of pharmaceutical pollutants from wastewater

“…18 For the C1s spectrum, the fitting revealed four peaks positioned at BEs of 284.6, 285.3, 286. 21 The interaction mechanism between the CoFe 2 O 4 NPs and AC is based on the random distribution of the ferrite NPs on the surface of the AC and the formation of a discrete coating, as illustrated in the SEM results. 22 This was also supported by the FTIR results in which the IR bands of the AC did not show a significant shift upon the addition of the CoFe 2 O 4 NPs (Fig.…”

Synthesis of Copper(II) Trimesinate Coordination Polymer and Its Use as a Sorbent for Organic Dyes and a Precursor for Nanostructured Material

“…When the solution reached a pre-determined temperature, an adsorbent (copper trimesinate synthesized by a method C, 0.1 g) was introduced and a timer was started. Every 15 min, 10 mL of a sorbent suspension in a dye solution was pipetted and centrifuged quickly; the concentration of residual dye was determined in the filtrate using a UV-visible spectrophotometer (Varian, Cary50) at λ max = 492 nm (CR) [69], 664 nm (MB) [70], 584 nm (MV) [71], respectively.…”
