In-Depth Sulfhydryl-Modified Cellulose Fibers for Efficient and Rapid Adsorption of Cr(VI).

As one of the hazardous heavy metal ion pollutants, Cr(VI) has attracted much attention in the sewage treatment research field due to its wide distribution range and serious toxicity. In this paper, cellulose fibers were prepared by wet spinning and followed by freeze drying, resulting in large porosity. Subsequently, in-depth sulfhydryl modification was applied with cellulose fibers for efficient and rapid adsorption of Cr(VI).

HTO/Cellulose Aerogel for Rapid and Highly Selective Li Recovery from Seawater.

To achieve rapid and highly efficient recovery of Li from seawater, a series of HTiO/cellulose aerogels (HTO/CA) with a porous network were prepared by a simple and effective method. The as-prepared HTO/CA were characterized and their Li adsorption performance was evaluated. The obtained results revealed that the maximum capacity of HTO/CA to adsorb Li was 28.
