PRODUCING METHOD OF BIOSORBENT FOR HEAVY METAL REMOVAL AND BIOSORBENT PRODUCED THEREFROM

摘要

The present invention relates to a method for producing a biological adsorbent for the removal of heavy metals and the bio adsorbent produced thereby, more particularly,; 1) a poly (vinyl alcohol) aqueous solution in step by mixing, heat the alginic acid or brown algae for producing a polyvinyl alcohol or alginic the brown algae is immobilized biological adsorbent precursor solution on;; 2) a step of adding the above step 1), the biological adsorbent precursor solution, xanthan gum, and surfactants and an aqueous solution of boric acid containing the glutaraldehyde in the production in, by modifying the surface of the biological adsorbent precursor to prepare a spherical biological adsorbent .; And; 3) it relates to a biological adsorbent manufacturing method, and thereby the biological adsorbent for After aging the biological adsorbent prepared in Step 2), was filtered, washed, to remove heavy metals which comprises the step of drying.
