Description
Technical field
The invention belongs to Material Fields, and in particular to a kind of trivalent chromium adsorbent and preparation method thereof.
Background technology
Chromium is one of main toxic metals of environmental pollution.Micro Cr3+Necessary to being human body, but Excess free enthalpy is meeting
Harm is generated, and have carcinogenesis to human body.And now multiple industries such as metallurgy, chemical industry, plating are all discharged largely daily
Chromate waste water, this heavy metal wastewater thereby are difficult to be degraded by microorganisms.At present the processing method of chromate waste water frequently with reduction neutralize,
It is the methods of ion-exchange, chromic acid precipitated barium and activated carbon adsorption, more for the treatment research of Cr VI in recent years, and it is right
It is less in the research of removal trivalent chromium.Although the toxicity of trivalent chromium is smaller than Cr VI, it can be to Cr VI in nature
Conversion, and the colloid in environment has trivalent chromium strong suction-operated, thus chromium can enter soil from water.It prevents from giving up
Chromium in water further generates pollution, while Cr VI is easily reduced into trivalent chromium, studies the removal meaning of trivalent chromium to soil
It is great.
