Abstract
The invention relates to a method for removing bromate in water, particularly to a method for removing bromate in water through Fe<2+> and beta-FeOOH supported red mud ceramsite, and aims to solve problems that the drug dosage is large and Fe<2+> and beta-FeOOH are loose in a powder shape and easy to hydrolyze when Fe<2+> and beta-FeOOH are added separately to remove the bromate in the water according to existing methods. The method comprises steps as follows: a certain amount of the Fe<2+> and beta-FeOOH supported red mud ceramsite is added to a to-be-treated bromate solution, a treated solution is obtained after vibration at a certain temperature, and the bromate concentration of the solution is measured. The bromate in the water is removed with the method.
Description
Technical field
The present invention relates to a kind of method removing bromate in water.
Background technology
Bromate has been 2B level potential carcinogen by international cancer research institution, and research shows, when to drink bromate concentration be throughout one's life the tap water of 5.0 μ g/L to people, its carcinogenic danger degree is 10
-1.At present for the removal technology of bromate, there is many research both at home and abroad.Wherein ferrous sulfate reduction method empirical tests can faster by BrO
3 -be reduced to Br
-, but Fe required in reaction process
2+concentration is higher, and iron level in water body can be caused after reaction to exceed standard.Therefore its load can be overcome the large problem of its throwing amount on haydite surface.
β-FeOOH is a kind of environmental friendliness shaped material, is widely used as sorbent material and makes a return journey the pollutent in dewatering.In ferriferous oxide, β-FeOOH, owing to having larger specific surface area, therefore has very strong adsorptive power.The starting raw material simultaneously producing it is cheap and easy to get, and therefore, the production cost of this sorbent material is low, has the extremely strong market competitiveness.In current research, β-FeOOH is proved to be exists ion exchange to bromate, has stronger adsorptive power.But add separately β-FeOOH as sorbent material, its dosage is large, and it is the application that Powdered loose facile hydrolysis limits it.
Red mud is the waste produced in aluminum oxide production process, utilizes it to be prepared into haydite with low cost.By Fe
2+the two dosage can be reduced on its surface with β-FeOOH load, the physicochemical property on red mud porcelain granule surface can be changed simultaneously, improve its combined adsorption and entrapment to bromate in water.
Summary of the invention
The present invention will solve existing method to add Fe separately
2+when removing bromate in water with β-FeOOH, added amount of chemical is large, and it is the problem of Powdered loose facile hydrolysis.And a kind of load Fe is provided
2+the method of bromate in water is removed with the red mud porcelain granule of β-FeOOH.
A kind of load Fe
2+the method removing bromate in water with the red mud porcelain granule of β-FeOOH is carried out according to the following steps:
Temperature be 15 DEG C ~ 35 DEG C and vibration condition under in containing the water of bromate, add load Fe
2+adsorb with the red mud porcelain granule of β-FeOOH, adsorption time is 1h ~ 4h, obtains processing rear solution; Described is 600 μ g/L ~ 1000 μ g/L containing the concentration of bromate in the water of bromate; The pH scope of the described water containing bromate is 5.8 ~ 8.8; Described load Fe
2+be 1g:(8 ~ 12 with the quality of the red mud porcelain granule of β-FeOOH and the volume ratio of the water containing bromate) mL.
Beneficial effect of the present invention:
1, operating process of the present invention is simple, can reach 91%, can effectively remove bromate in water to the clearance of bromate.Main mechanism is that adsorption, ion exchange and reductive action combine.Fe
2+playing its effect with β-FeOOH by loading to red mud porcelain granule puts in water again, reducing its dosage, it also avoid the feature of loose facile hydrolysis.Fe
2+improve specific surface area and the absorption property of red mud porcelain granule with the load of β-FeOOH, add its reducing power, make it effectively remove bromate in water.
