Compositions for bromide removal include a two-dimensional material impregnated with silver. The silver may be impregnated in the two-dimensional material by contacting the two-dimensional material with silver ions in an aqueous solution, allowing the silver ions to adsorb on the two-dimensional material, and drying the two-dimensional material. Removing bromide from an aqueous composition including bromide may include contacting the aqueous composition with a two-dimensional material impregnated with silver, and allowing the bromide to react with the silver to yield silver bromide.

Silver-impregnated two-dimensional structures for bromide removal

Wastewater sludge is treated by combining the sludge with a carbon-based dielectric additive that includes carbon to yield a modified sludge, irradiating the modified sludge with microwave radiation to yield a treated sludge, and providing the treated sludge to an anaerobic digester.

Additive-amplified microwave pretreatment of wastewater sludge

A soil remediation method for treating contaminated soil includes combining a dielectric carbonaceous nanomaterial with the contaminated soil to yield a composite contaminated soil, and irradiating the composite contaminated soil with microwave radiation to yield a remediated soil. The composite contaminated soil includes at least 1 wt % of the dielectric carbonaceous material, and the microwave radiation provides an energy input of at least 2.5 kWh per kilogram of the composite contaminated soil.
