- A preorganized structure with two positive nitrogen ions linked by a carbon atom was designed. This structure acts like crab pincers to tightly entrap chromate. The adsorbent based on the designed structure incorporated into graphene oxide (PS-GO) has a dramatically enhanced binding affinity to Cr(vi) under neutral conditions.
