Sulfur rich microporous polymer enables rapid and efficient removal of mercury(II) from water.

Design and synthesis of adsorbents for efficient decontamination of hazardous contaminants Hg from wastewater, based on a facile and economical strategy, is an attractive target. Here, a novel sulfur rich microporous polymer (sulfur content of 31.4 wt %) with high surface area as well as densely populated sulfur atom with fast accessibility was reported to remove mercury (II) from water.
