“…The most important reason for applying the RAFT polymerization was to provide uniformity across the MIP network and it was indicated by the m value that RAFT mechanism effectively ensures the achievement of a well-ordered structure. This result is in agreement with previously published works [11,67,70,74,75]. Kinetics of adsorption is important since it explains the adsorption behavior and controls efficiency.…”

“…The heterogeneity index, n which varies in the range of 0-1 was determined as 0.13. The value of n shows an increase with an increase in homogeneity of the system and it equals to the 1 for an ideal homogeneous system [24]. As can be noticed the MIM prepared by conventional free radical polymerization method has a heterogeneous nature due to the polymerization method [25].…”

S ince its discovery, penicillin G has been useful for the treatment of infectious diseases in humans and animals. This compound is one of the most widely used drugs among antibiotics. Unfortunately, there is a continuous release of antibiotics due to the widespread and overuses of this family of the drug in some certain places such as hospitals and farms. Release of antibiotics to environmental waters is a crucial problem for human health. The residues of antibiotics were detected in industrial and municipal wastewater, and also surface and groundwater samples [1][2][3][4]. The residues of antibiotics in environmental waters may cause the development of antibiotic resistance [5]. The recognition and removal of the antibiotics from environmental water are necessary to protect public health by using easy, compatible, cheap and reliable materials.There are several sensing and recognition systems for Penicillin G prepared by utilizing molecularly imprinting method [6][7][8]. Most of them are related by detecting of antibiotics from complex matrices such as food and food derivatives like milk, chicken, etc. [8,9]. The production methods includes synthesis of nanopolymers by emulsion polymerization [9], surface imprinting onto various support materials like magnetic nanoparticles [10] or non-woven fabrics [11]. Unfortunately,

“…Although conventional graft copolymerization is very effective in changing the surface properties, it is quite insufficient in making this change in a controlled way. It is not possible to adjust a number of properties, particularly the molecular weights and architectures of polymer chains grafted to substrate via the conventional free radical graft copolymerization techniques [ 9 , 12 , 13 ]. Especially in the case of confined spaces such as nano-sized channels, as with TeM’s, using traditional grafting methods can lead to their plugging, which means losing the most basic advantage, i.e., high surface area, from the beginning [ 12 ].…”

Nanoporous track-etched membranes (TeM) are promising materials as adsorbents to remove toxic pollutants, but control over the pore diameter and density in addition to precise functionalization of nanochannels is crucial for controlling the surface area and efficiency of TeMs. This study reported the synthesis of functionalized PET TeMs as high-capacity sorbents for the removal of trivalent arsenic, As(III), which is more mobile and about 60 times more toxic than As(V). Nanochannels of PET-TeMs were functionalized by UV-initiated reversible addition fragmentation chain transfer (RAFT)-mediated grafting of 2-(dimethyamino)ethyl methacrylate (DMAEMA), allowing precise control of the degree of grafting and graft lengths within the nanochannels. Ag NPs were then loaded onto PDMAEMA-g-PET to provide a hybrid sorbent for As(III) removal. The As(III) removal efficiency of Ag@PDMAEMA-g-PET, PDMAEMA-g-PET, and pristine PET TeM was compared by adsorption kinetics studies at various pH and sorption times. The adsorption of As(III) by Ag@DMAEMA-g-PET and DMAEMA-g-PET TeMs was found to follow the Freundlich mechanism and a pseudo-second-order kinetic model. After 10 h, As(III) removal efficiencies were 85.6% and 56% for Ag@PDMAEMA-g-PET and PDMAEMA-g-PET, respectively, while PET template had a very low arsenic sorption capacity of 17.5% at optimal pH of 4.0, indicating that both PDMAEMA grafting and Ag-NPs loading significantly increased the As(III) removal capacity of PET-TeMs.
