“…Alginate and derived adsorbents are frequently used in the treatment of water and wastewater contaminated by toxic heavy metals. For example, alginate beads have been widely studied for Pb(II) adsorption [8,10,52,55,72], in the treatment of Cu(II) and Cd(II) ions [11,52,53,73], alginate modified for efficient sorption of Cd(II), Cu(II), Pb(II), Zn(II), Ni(II) and Hg(II) [73][74][75], in the trapping of Hg(II), Cd(II), Pb(II) and Zn(II) [12], for U(VI) [76], As(V) [77,78], and Cr(VI) [79]. Composites based on chitosan and alginate play a central role in increasing the adsorption capacity.…”

Owing to environmental pollution and increasingly strict regulations, heavy metals have attracted the attention of many researchers in various disciplines. Alginate and chitosan derivatives have gained popularity as biosorbents for water treatment. An increase in the number of publications on modified biosorbents for the biosorption of toxic compounds reveals widespread interest in examining the requirements and positive contribution of each modification type. This paper reviews the advantages and disadvantages of using alginate and chitosan for adsorption. Well-known modifications based on chitosan and alginate, namely, grafting, functionalization, copolymerization and cross-linking, as well as applications in the field of adsorption processes, especially amino acid functionalization, are reviewed. The selection criteria for the best biosorbents and their effectiveness and proposed mechanism of adsorption are discussed critically. In the conclusion, the question of why these adsorbents need modification before use is addressed.

Biopolymer‐Aerogele gehören zu den ersten Aerogelen, die hergestellt wurden, aber erst im letzten Jahrzehnt kam es zu einer Belebung der Forschung über Biopolymer‐ und Biopolymer‐Verbundstoff‐Aerogele, die durch Fragen der Nachhaltigkeit, einstellbare spezielle Eigenschaften und einfache Funktionalisierung motiviert wird. Biopolymer‐Aerogele und offenzellige Biopolymer‐Schäume haben Potenzial für klassische Aerogel‐Anwendungen wie Wärmedämmung und neue Anwendungen bei der Filtration, Öl‐Wasser‐Trennung, CO2‐Abscheidung, Katalyse und in der Medizin. Das Gebiet der Biopolymer‐Aerogele wird heute von der empirischen Materialentwicklung auf dem Labormaßstab beherrscht und benötigt eine bessere theoretische Grundlage und Test in Pilotanlagen. Unser Aufsatz umfasst eine Datenbank mit über 3800 Biopolymer‐Aerogel‐Eigenschaften, beurteilt den Forschungsstand auf dem Gebiet und diskutiert wissenschaftliche, technologische und wirtschaftliche Hindernisse bei der Kommerzialisierung dieser faszinierenden Materialien.

Biopolymer aerogels were among the first aerogels produced, but only in the last decade has research on biopolymer and biopolymer-composite aerogels become popular, motivated by sustainability arguments, their unique and tunable properties, and ease of functionalization. Biopolymer aerogels and open-cell foams have great potential for classical aerogel applications such as thermal insulation, as well as emerging applications in filtration, oil-water separation, CO capture, catalysis, and medicine. The biopolymer aerogel field today is driven forward by empirical materials discovery at the laboratory scale, but requires a firmer theoretical basis and pilot studies to close the gap to market. This Review includes a database with over 3800 biopolymer aerogel properties, evaluates the state of the biopolymer aerogel field, and critically discusses the scientific, technological, and commercial barriers to the commercialization of these exciting materials.
