“…Besides the direct chemical modification, literature reveals the grafting of various monomeric units like acrylic acid, acrylamide, acrylonitrile, ethylenediamine, hydroxylamine, glycidyl monomers, urea, etc. followed by functionalization of the biomass surface so as to develop a better biosorbent [206][207][208][209]. Graft co-polymerization is a process in which an additional polymer is introduced into the backbone of the main polymeric chain.…”

The biosorption process has been established as characteristics of dead biomasses of both cellulosic and microbial origin to bind metal ion pollutants from aqueous suspension. The high effectiveness of this process even at low metal concentration, similarity to ion exchange treatment process, but cheaper and greener alternative to conventional techniques have resulted in a mature biosorption technology. Yet its adoption to large scale industrial wastewaters treatment has still been a distant reality. The purpose of this review is to make in-depth analyses of the various aspects of the biosorption technology, staring from the various biosorbents used till date and the various factors affecting the process. The design of better biosorbents for improving their physico-chemical features as well as enhancing their biosorption characteristics has been discussed. Better economic value of the biosorption technology is related to the repeated reuse of the biosorbent with minimum loss of efficiency. In this context desorption of the metal pollutants as well as regeneration of the biosorbent has been discussed in detail. Various inhibitions including the multi mechanistic role of the biosorption technology has been identified which have played a contributory role to its non-commercialization.

“…Selulosa adalah polisakarida dan berat molekul tergantung pada sumber selulosa tersebut serta kondisi dan teknik isolasinya [1]. Teknik kopolimerisasi cangkok telah dimanfaatkan antara lain untuk mengubah sifat polimer induk dengan berbagai tujuan antara lain sebagai adsorben ion logam [2,3]. Dalam kopolimerisasi cangkok, rantai samping cangkok dengan kelompok fungsional kovalen melekat pada rantai utama dari backbone polimer untuk membentuk kopolimer bercabang [4].…”

MODIFIKASI SELULOSA MENGGUNAKAN ASAM AKRILAT DAN TRIMETHALLYL ISOCIANURATE DENGAN METODE PRA IRADIASI PEROKSIDA. Modifikasi selulosa dengan asam akrilat menggunakan pengikat silang Trimethallyl Isocianurate (TMAIC) dengan teknik kopolimerisasi cangkok pra-iradiasi-peroksida telah berhasil dilakukan. Penelitian ini bertujuan untuk mendapatkan adsorben ion logam berbasis selulosa. Pengikat silang TMAIC digunakan untuk meningkatkan ketahanan asam dan termal dari selulosa-g-AA. Kondisi optimum reaksi pencangkokan diperoleh pada dosis radiasi 40 kGy, konsentrasi TMAIC 0,5 %(w/v), konsentrasi monomer 10 %(v/v), suhu pencangkokan 90°C dan waktu pencangkokan 6 jam, dengan persen pencangkokan rata-rata sebesar 42,37 %. Pengembangan dalam air turun sebesar 36 % setelah penambahan TMAIC. Hasil sintesis kopolimer selulosa-TMAIC-g-AA telah berhasil dikarakterisasi dengan FT-IR, TGA dan SEM. Selulosa terikat silang dapat digunakan sebagai adsorben ion logam Pb 2+ , dengan kapasitas adsorpsi sebesar 2,60 mg/g pada waktu kontak 2 jam dan pH 5 (konsentrasi awal Pb 2+ 10 mg/L). Isoterm adsorpsi yang sesuai dengan adsorpsi Pb(II) dengan kopolimer adalah isoterm adsorpsi Langmuir yang berarti energi adsorpsi konstan di semua sisi kopolimer tersebut.
