An apparatus for treating an aqueous solution containing arsenic. The apparatus comprises a container that includes a housing, an inlet located at a first end of the housing and an outlet located at a second end opposite the first end. An outer wall extends between the first and second ends and enclosing a fluid flow path between the inlet and the outlet and an arsenic fixing agent is disposed in the fluid flow path. The arsenic fixing agent can include an insoluble rare earth-containing compound, more specifically, a compound comprising one or more of cerium, lanthanum, or praseodymium. The inlet and the outlet are adapted to be closed during transport and storage. The container is adapted to be sealed for long term disposal after exposure to an aqueous solution containing arsenic.
What is claimed is: 1. A container adapted for treating an aqueous solution containing arsenic, the container comprising:sealant introduction means for introducing, after removing the arsenic from the aqueous solution, a sealant into one or more spaces of the container;a housing having an inlet loca
What is claimed is: 1. A container adapted for treating an aqueous solution containing arsenic, the container comprising:sealant introduction means for introducing, after removing the arsenic from the aqueous solution, a sealant into one or more spaces of the container;a housing having an inlet located at a first end and an outlet located at a second end opposite the first end, one or more outer walls extending between the first and second ends enclosing a fluid flow path between the inlet and the outlet; andan insoluble rare earth-containing arsenic fixing agent disposed within the housing in the fluid flow path for treating a flow of the aqueous solution containing arsenic, wherein the arsenic fixing agent is spaced apart from at least one of the inlet, outlet and the outer walls to define the one or more spaces, the one or more spaces are positioned between the arsenic fixing agent and the at least one of the inlet, outlet and the outer walls, the one or more spaces adapted for receiving the sealant and sealing the container for disposal after substantially removing the arsenic from the aqueous solution.
