“…In this Ref. [27], the anion exchange resin D201×7 (strongly basic styrene-based anion exchange resin with quaternary ammonium group (R 3 R ′ -N + being R = CH 3 and R ′ = Cl) and chloride as counter-anion) has been used to separate germanium from a sulfuric solution, using tartaric acid as a complexing agent. In the sulfuric acid system, Ge(OH) 4 was converted to an anionic complex [GeO 2 (OH) 2 C 4 H 4 O 4 ] 2− at a 1:1 tartaric acid-to-metal molar ratio, and thus, the resin uptakes this anionic complex.…”

“…In this reference [23], the anion exchange resin D201×7 (strongly basic styrene-based anion exchange resin with quaternary ammonium group (R3R´-N + being R= CH3 and R´= Cl) and chloride as counter-anion) has been used to separate germanium from a sulfuric solution using tartaric acid as a complexing agent. In the sulfuric acid system, Ge(OH)4 was converted to an anionic complex [GeO2(OH)2C4H4O4] 2− at a 1:1 tartaric acid to metal molar ratio, and thus, the resin uptakes this anionic complex.…”
