Efficient removal of Pb(II)/Cu(II) from aqueous samples by a guanidine-functionalized SBA-15/Fe3O4

Natural and Synthetic Polymers Modified with Acid Blue 113 for Removal of Cr3+, Zn2+ and Mn2+

“…Therefore, they contained functional groups that strongly interacted with M X+ establishing complex combinations. Many studies have been reported for separation of metal ions from aqueous medium using chelate polymers [ 5 , 6 ]. In this, chelate resins applied for metal ions removal present a multitude of advantages: (i) the selectivity of chelate resin for one and more metal ions (given by the affinity of the ligand immobilized in the resin for M X+ ), (ii) the organic reagent can be removed from the resin and the resin can be recovered and reused and the economical aspect can be taken into consideration; (iii) the impregnation of the resin can be performed in accessible working conditions; (iv) chelate resin has a good stability in acidic medium; and (v) offers a good capacity for M X+ removal [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ].…”

Efficient Photodegradation of Eriochrome Black-T by a Trimetallic Magnetic Self-Synthesized Nanophotocatalyst Based on Zn/Au/Fe-Embedded Poly(vinyl alcohol)

“…The peak that emerged at 2340 cm –1 in Figure a­(i,ii) is attributed to the atmospheric CO 2 . Also, the peaks at 580 and 630 cm –1 are distinctive peaks for metal–oxygen (Fe–O) stretching vibration modes. , These peaks are characteristically marked for all spinel structures and ferrites. The distinctive ZnO NRs’ functional groups are exhibited in Figure a­(ii).…”

“…Over the last few decades, along with industrial advances, ignoring safety principles, and emancipation of industrial waste in the water stream, we have observed a dreadful industrial contaminant increase, such as organic and inorganic dyes on earth, which are easily soluble in water and perilously threaten human health. , Hence, novel and efficient approaches for chemical pollutant removal or degradation have been investigated. Various routes have been proposed to eliminate risky metal ions, viz., copper­(II), chromium­(VI), etc., and dyes, such as methylene blue, methyl orange, etc. − For example, Maleki et al have designed an efficient nanocomposite comprised of CdS/Cu­(OH) 2 /CuO@PVA-Chl to effectively degrade methylene blue­(MB), Congo red (CR), and 4-chlorophenol (4-CP) dyes in aqueous solutions . Besides, the reactive black 5 was removed via photocatalytic degradation by Bi 2 O 3 -decorated porous g-C 3 N 4 sheets as reported by Shafawi et al Even natural-based materials have been dedicated to Eriochrome black-T (EBT) degradation, as Borhade et al have introduced a calcium oxide-containing Mercenaria shell powder prepared by a mechanochemical approach for EBT’s photocatalytic degradation.…”

Synergies in antimicrobial treatment by a levofloxacin-loaded halloysite and gold nanoparticles with a conjugation to a cell-penetrating peptide

“…According to the literature, several factors can affect the patterns and induce shiing in the location of the XRD peaks. 84,85 There is also another peak in the pattern of lvx@HNT/ Au-CPP that has appeared at 2q ¼ 12.2 . This peak can be attributed to the new phase formed on the surface of HNTs through MPS-coating.…”
