Adsorbentien aus nachwachsenden Roh- bzw. Reststoffen für Anwendungen in der Abwasserbehandlung: Korrelation von Adsorptionsverhalten und chemischer Struktur

When thinking about a more sustainable world, it is enormously important to obtain chemical resources primarily from renewable raw materials. One possible candidate that can also be used in the long term in a wide variety of preliminary stages in the chemical industry is lignin. To this end, doctoral student Jonas Bergrath is looking at various biogenic wastes (including waste wood and pomace from winegrowing) in order to isolate lignin in as "green" a way as possible. Since lignin is extremely difficult to reproduce, he uses a wide range of analytical and computational chemistry methods to reveal possible structure-property correlations. The overall goal is to relate the physico-chemical properties (including adsorption and behaviour in solvents) to structural elements of lignin and to use it as an adsorbent for organic small molecules (e.g. pharmaceuticals) in wastewater treatment.
