“…The simplest interpretation of these experiments is that the fractionation of magnesium isotopes occurs in growth of the cyanobacteria and synthesis of chlorophyll- The step that causes fractionation in chlorophyll synthesis is unknown, but we suspect that it is related to a chelation step, since it is well documented that chelation can cause fractionation of magnesium isotopes on resins (Chang et al, 2003;Kim et al, 2002;2003;Kim and Kang, 2001). The precise mechanism for insertion of magnesium into the tetrapyrrole ring (protoporphyrin IX, Figure 1) during the biosynthesis of chlorophyll is not known.…”

Polymeric resin has shown great application in recovery the lithium ion from aqueous solution due to their structure's tunability and reusability. However, the conventional resins such as commercial HYC-100 is suffering by its low lithium adsorption capacity and slow inclusion rate. Herein, a series of HYC-100 modified resins (MRs) using oligo(ethylene glycol) as crosslinker were synthesized and their adsorption capacities for lithium ion in aqueous solution (pH 9.1, ionic concentration 500 mg/L, 25 C) were determined by adding 1 g resin to 500 mL lithium chloride aqueous solution. The new formed cyclic structure from oligo(ethylene glycol) provides lithium ion binding sites which play an important role for lithium ion adsorption. The tri(ethylene glycol) modified resin (3EGMR) showed the highest capacity to be 18 mg/g, which was three times more than that of HYC-100 (5 mg/g). Therefore, Scale-up experiment was conducted by using 20 L reactor and the adsorption capacity is satisfactory. This work might pave a new avenue to develop new polymeric resin to enhance the lithium ion adsorption performance.
