Germanium (Ge) is one of the critical elements that lack an efficient economic recovery process from dilute sources. An improved catechol-based adsorbent, catechol-functionalized chitosan (C–), was synthesized to recover germanium (Ge) from dilute acidic solutions.

Therefore, organic germanium is a kind of "internal Chizhevsky chandelier" [10, 11]. At the same time, organic germanium compounds are nontoxic, they have no side reactions and function in the body for a long time, and hence can be regarded as extremely prom-ising for use in medicine [5, 6]. Dolaychuk et al. [13] reported the results of ...
