Abstract: Disclosed are a transition metal-doped carbon microsphere, a preparation method therefor and an application thereof. The transition metal-doped carbon sphere has a uniform solid porous structure, and the transition metal is uniformly distributed inside the carbon sphere. The preparation method comprises that a carbon microsphere uniformly doped with manganese, vanadium, molybdenum and tungsten is prepared by means of a one-step hydrothermal method, is mixed with potassium oxalate, and is roasted in a protective atmosphere to obtain an activated metal-doped carbon sphere. The doped transition metal elements remain uniformly dispersed after being roasted, and do not agglomerate. The transition metal-doped carbon microsphere obtained has the following characteristics: it exhibits good adsorption properties for heavy metal ions Cr(VI), with the maximum adsorption amount being 660.7 mg/g; it can achieve advanced removal of Cr(VI) from the wastewater of which the initial Cr(VI) concentration is lower than 200 mg/L, with the residual Cr(VI) concentration after adsorption being lower than 0.05 mg/L; and it shows good application prospect in the treatment of wastewater containing heavy metal.

Abstract: Systems and methods for generating a brine solution using a salt bag for recharging zirconium phosphate in a reusable sorbent module are provided. The salt bag can be a double layer bag. An inner water permeable bag can contain solid salts and can be surrounded by an outer water impermeable bag. Water can be added to dissolve the salts in the inner bag and the resulting solution can be collected as a brine solution for use in recharging the zirconium phosphate.

Abstract: The present application relates to activated carbon compositions for removing viral, bacterial, or other infectious particles from air. The activated carbon was found to be effective at filtering aerosolized bacteriophage particulates and could be applied to barrier materials which prevents viral particulates from passing through, for example in home filters or masks or other coverings to prevent the spread of infectious diseases.

Abstract: A synergistic composition can be used to treat water containing nitrogen compounds and phosphorus compounds. The synergistic composition includes iron filings, clay particles, aluminum particles, and sand particles. The iron filings, clay particles, and aluminum particles act synergistically to remove nitrogen compounds and phosphorus compounds from water. Specifically, the clay particles attract the nitrogen compounds and the phosphorus compounds to be absorbed onto a surface of the iron filings and the clay particles. The aluminum particles react with the nitrogen compounds via an oxidation reaction to form ammonia compounds, and react with the phosphorus compounds to produce aluminum phosphate. As such, the synergistic relationship between the iron filings, clay particles, and aluminum particles remove nitrogen and phosphorus compounds from water and recover the compounds in usable forms, namely, ammonia and aluminum phosphate.
