Abstract

The invention discloses a composite absorbing material for removing germanium ions from a natural water body, and a preparation method of the composite absorbing material, and belongs to the field of material preparation. The preparation method comprises the steps of heating agarose powder in a buffer solution to prepare an agarose gel solution, cooling and solidifying to obtain agarose gel, adding thioglycollic acid and tetrahydrofuran for mixing, adding a drop of concentrated sulfuric acid and then agarose gel for stirring and backflow, cooling to a room temperature, conducting suction filtration, washing with deionized water to be neutral, washing with a little alcohol, drying and then obtaining the adsorbing material with a sulfydryl load surface and good selective adsorption performance on the germanium ions. The preparation method has the characteristics of innovation, novelty and uniqueness, and the prepared material has a good absorbing effect on the germanium ions in the water.

Description

technical field [0001] The invention relates to a composite adsorption material for removing germanium ions in natural water bodies and a preparation method thereof, in particular to advanced treatment of water bodies containing germanium ions, and belongs to the field of waste water treatment in environmental protection. Background technique [0002] Germanium is widely used in electronics, atomic energy industry and other fields, and has important economic value. Except for a small part of germanium existing in independent minerals, most of germanium is usually associated with lead-zinc ore, which is a typical scattered element. Germanium can also be used in optical fibers, catalysts and infrared materials. The Gulf War demonstrated the power of germanium infrared materials, and countries competed to arm themselves with high technology, and the amount of germanium used in infrared materials increased year by year. As the amount of PET increases, the use of germanium as a...
