Method for adsorption and separation of heavy metals using an adsorbent and tannin adsorbent regeneration method.

摘要

A method for adsorbing and removing HEAVY METAL ELEMENT USING Tannin adsorber comprising: (A) adjusting the pH to a solution containing a plurality of elements HEAVY METAL A predetermined pH; (B) contacting the adsorbent with the solution in which it is adjusted the pH thereof; (C) adjusting the pH of the solution contacted with the adsorbent TO A DIFFERENT PH PH OF DEFAULT; And (d) contacting the solution that is set PH OF THE SAME IN EL PASO (D) with the adsorbent prepared in Step (A). ACCORDING TO method of the invention, all elements HEAVY METAL can be separated and adsorbed EFFECTIVELY USING adsorbing Tannin FROM A solution containing a number of elements HEAVY METAL. Also it disclosed a method of regenerating an adsorbent Tannin.
