The present study aims to investigate the adsorption of synthesized poly(2-acrylamide-2-methylpropane sulfonic acid) (PAMPs) onto alumina nanoparticles and their application in removal ciprofloxacin (CFX) antibiotic from a water environment. PAMPs were successfully characterized by nuclear magnetic resonance gel-permeation chromatography methods. number- weight-average molecular weights 6.76 × 105 7.28 106 g/mol, respectively. charge reversal nanoalumina after modification positive −37.5 mV...
Abstract Gas marbles are a new family of particle‐stabilized soft dispersed system with soap bubble‐like air‐in‐water‐in‐air structure. Herein, stimulus‐responsive character is successfully introduced to gas marble for the first time using polymer particles carrying poly(tertiary amine methacrylate) (p K ≈7) steric stabilizer on their surfaces as particulate stabilizer. The exhibited long‐term stability when transferred onto planar surface liquid water, provided that solution pH subphase...
Abstract Highly positively charged poly(vinyl benzyl trimethylammonium chloride) (PVBMA) was successfully synthesized with approximately 82% of yield. The PVBMA characterized by the molecular weight ( M w ) 343.45 g mol −1 and distribution, Đ 2.4 1 H NMR SEC measurements. applied as an effective agent for α‐Al 2 O 3 surface modification in adsorptive removal azo dye acid orange G (AOG). AOG performance significantly enhanced at all pH compared to without modification. experimental parameters...
Cationic random copolymers (PCm) consisting of 2-(methacryloyloxy)ethyl phosphorylcholine (MPC; P) with methacroylcholine chloride (MCC; C) and anionic (PSn) MPC potassium 3-(methacryloyloxy)propanesulfonate (MPS; S) were prepared via a reversible addition–fragmentation chain transfer method. "m" "n" represent the compositions (mol %) MCC MPS units in copolymers, respectively. The degrees polymerization for 93–99. Water-soluble unit contains pendant zwitterionic group whose charges are...
A diblock copolymer (P(VBTAC/NaSS)17-b-PAPTAC50; P(VS)17A50) composed of amphoteric random copolymer, poly(vinylbenzyl trimethylammonium chloride-co-sodium p-styrensunfonate) (P(VBTAC/NaSS); P(VS)) and cationic poly(3-(acrylamidopropyl) chloride) (PAPTAC; A) block, poly(acrylic acid) (PAAc49) were prepared via a reversible addition−fragmentation chain transfer radical polymerization. Scrips V, S, represent VBTAC, NaSS, PAPTAC blocks, respectively. Water-soluble polyion complex (PIC) vesicles...
Polyion complex (PIC) micelles having a hydrodynamic radius of approximately 20 nm were prepared in water by simply mixing pair double hydrophilic oppositely charged diblock copolymers composed first block containing pendant phosphobetaine groups and second cationic or anionic styrene-based polyelectrolyte block. The PIC stable under high salt concentration because the formation was driven both electrostatic hydrophobic interactions.
Amphoteric diblock copolymers (S10Vn, n = 5, 10, and 20) composed of anionic poly(sodium p-styrenesulfonate) cationic poly(vinylbenzyl trimethylammonium chloride) blocks were prepared via a controlled radical polymerization method. S10V10 was insoluble in pure water owing to its electrostatic interactions, but S10V5 S10V20 soluble water. exhibited upper critical solution temperature behaviors, the transition decreased with increasing sodium chloride concentration. The equimolar oppositely...
Adsorption of the cationic dye, Rhodamine B (RhB) onto surfactant modified laterite (SML) was studied in this work. The removal efficiency RhB using increased significantly after surface modification by pre-adsorption anionic sodium dodecyl sulfate (SDS). Some effective parameters such as pH, adsorbent amount and ionic strength were also investigated. optimal conditions for SML found to be pH 4, 0.1 g mM NaCl. Under optimum conditions, from 25.77% 94.85% compared without SDS modification....
Poly(4-((3-methacrylamidopropyl)dimethylammonium)butane-1-sulfonate) (PSBP) was prepared via controlled radical polymerization. PSBP showed upper critical solution temperature (UCST) behavior in aqueous solutions, which could be by adjusting the polymer and NaCl concentrations. Owing to its pendant sulfonate anions, exhibited a negative zeta potential of -7.99 mV formed water-soluble ion complex with cationic surfactant cetyltrimethylammonium bromide (CTAB) attractive electrostatic...
