Progress in pectin based hydrogels for water purification: Trends and challenges

Abstract

Pectin is one of the finest natural polymer which has drawn great attention because of its applications in different fields. Due to the quintessential structure of pectin, it can be transformed into variety of useful products. It can be utilized as a blend in many polymers to make a mixture or a composite material. Owing to considerable collection in chemical conformation and crosslinking mechanism, different pectin based hydrogels have been prepared for different characteristics in pharmaceutical and bio-medical sites. Inventive properties of hydrogels like volubility, swellability, solvability and hydrophilicity make them better alternative for wastewater treatment. Recently, pectin based hydrogels have demonstrated excellent performance to eliminate various metal ions and dyes from the polluted water. The adsorption

Natural biopolymer‐based hydrogels for use in food and agriculture

“…reviewed the beneficial properties of cellulose‐based superabsorbent hydrogels and their use for biomedical applications, in agriculture, for personal healthcare products and in water treatment. Thakur et al . also reviewed the use of pectin‐based hydrogels in water purification to eliminate toxic pollutants such as Pb(II), Cu(II), and Co(II).…”

Biomass-Derived Production of Itaconic Acid as a Building Block in Specialty Polymers

“…An essential application of biodegradable acrylamide hydrogels that include IA and itaconate groups in super absorbent hydrogels is in water-decontamination due to outstanding features such as low-price, precise handling, and reusability [124,134,135]. Water pollution presents a major worldwide problem that has caused serious environmental and health effects [136].…”

In situ forming microporous gelatin methacryloyl hydrogel scaffolds from thermostable microgels for tissue engineering

“…Hydrogels sourced from natural and/or synthetic materials have leveraged technologies pertinent to water treatment, energy storage, food security, and healthcare. [1][2][3][4][5][6][7] Granular hydrogel scaffolds have introduced emerging opportunities for developing in vitro tissue/disease models as well as in vivo therapies in regenerative medicine [8][9][10][11] owing to their unique structural features, particularly interconnected pores that promote cellular infiltration and enhance tissue remodeling. 12,13 The success of such scaffolds relies on their capability to overcome some of the key shortcomings of bulk hydrogels, mainly unconnected nanoscale pores that are 2-3 orders of magnitude smaller than the cell size.…”
