In recent years with the rapid economic globalization, pollution by industries and agriculture has increased, which results in decrease in the quality of ground and surface water. Pollution by heavy metals has become a serious health issue worldwide due to their nonbiodegradable and persistent nature. Therefore, extensive research has been done to develop ecofriendly and effective methods for removal of heavy metals, such as chemical precipitation, ion exchange, electrodialysis, membrane filtration, and adsorption. Among these methods, adsorption is the most recognized technique for wastewater treatment due to high-removal efficiency and ease in operation without yielding harmful by-products. Recently, nanocomposites based on biopolymer-grafted synthetic adsorbent have been used in various industrial applications including wastewater treatment. Therefore, the present chapter will be devoted for the removal of toxic heavy metals from wastewater by using bionanocomposite.

“…CTS consisting of glucosamine and N‐acetylglucosamine units is also cationic polysaccharides having the good biocompatibility and low toxicity . Therefore, it is regarded as an attractive polymer for the biomedical applications . CTS was modified by grafting of GMA having reactive epoxy and acrylic groups to form not only water‐soluble derivative but also photocurable groups on its backbone .…”

Herein, a new approach was applied to produce reduced graphene oxide (RGO)‐based conductive hydrogel by using modified chitosan (CTS) as a primary constituent. A variety amounts of RGO (from 0 to 15%) were incorporated into the polymeric network generated by photopolymerization of CTS‐graft‐glycidyl methacrylate (CTS‐g‐GMA) and poly(ethylene glycol)diacrylate (PEGDA). The structures of hydrogels were confirmed by FT‐IR, XRD, and SEM analyses. Water uptake capacity of hydrogels determined gravimetrically. L929 fibroblast cells were used for cytotoxicity test. According to conductivity measurements carried out by four‐point probe technique, the highest conductivity (1.716 × 10−3 S/cm) was obtained when 10% RGO was encapsulated into the polymeric structure. From the results, it could be envisaged that electroconductive hydrogel (ECH) fabricated in this study could have a potential usage for biosensor applications in the future projects. © 2019 Wiley Periodicals, Inc.

“…Extensive research works have been carried out to develop NF/UF membranes that can be used to fulfill the above separations . Although commercial polymeric membranes are readily available in the market such as cellulose acetates, polyethersulfones, polysulfones, and polyacrylonitrile, but these membranes usually have fixed physico‐chemical properties which limit any separation to the fixed selectivity of their constituents . Amongst the new generation of intrinsic conducting polymer membranes, polyaniline (PANI) has captured the intense attention of the scientific community as one of the promising alternative candidates to commercial membranes .…”

A pressure filtration membrane from conducting polymer polyaniline (PANI) is known to possess low mechanical strength and thermal stability. Therefore, it is believed that the properties of the membrane can be enhanced by blending PANI with a conventional polymer like polyimide (PI), which possesses high mechanical strength and thermal stability. A thermal analysis revealed that polymer chain of blend membranes started to break beyond the melting temperature of pure PANI membrane indicating that the addition of PI hindered the degradation of PANI and thus slowed down the decomposition process. Mechanical tests further showed that PANI/PI membrane had a tensile strength that was 60% higher than pure PANI membrane. Furthermore, the surface hydrophilicity and negativity of the blend membrane increased as it was doped in acid, thereby reflecting the exploitation of advantages of both polymers. Rejection at various molecular ranges of PEGs showed that PANI/PI membrane was initially in the ultrafiltration (UF) range, but later fell into the nanofiltration (NF) range when an acid dopant was introduced to the membrane. According to the long‐term filtration performance, the PANI/PI membrane was able to sustain a rejection of up to 99% in Congo red solution with just a slight reduction in flux. POLYM. ENG.
