    摘要: A water treatment system including: a flow regulation control system configured to combine oxo-anion-contaminated water with a reduction-promoting agent, a hole scavenger, or both; a reactor fluidically coupled to the flow regulation control system; a first set of system control probes configured to monitor the concentration of oxygen and oxo-anion in the contaminated water; a second set of system control probes configured to monitor concentration of the oxo-anion and reduction products of the oxo-anion in treated effluent from the reactor; and a controller configured to control the flow regulation control system, thereby controlling the flow rate of the contaminated water and the at least one of the reduction-promoting agent and the hole scavenger to the reactor based at least in part on the concentration of oxo-anion and the reduction products of the oxo-anion in the treated effluent.

    摘要: Preparing a porous hybrid media includes contacting porous media (e.g., strong base ion-exchange media) with an aqueous solution including aluminum ions to yield a aluminum-ion-containing porous media, contacting the aluminum-ion containing porous media with a reducing agent to impregnate elemental aluminum in the porous media, and oxidizing the elemental aluminum to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. In some cases, a pH of an aqueous mixture including the aluminum-ion-containing porous media may be adjusted to form a floc including aluminum hydroxide, and the aluminum hydroxide-containing porous media may be contacted with a reducing agent to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. The porous hybrid media may advantageously be prepared at low temperature (e.g., room temperature).
