Chicken manure biochar activated by phosphoric acid and method for removing lead using the same

摘要

The present invention relates to a biochip with enhanced biochannel removal ability by activating biochar made by pyrolyzing chicken manure with phosphoric acid, a method for producing the same, and a method for removing lead using the same. The phosphoric acid-activated biochain according to the present invention has improved lead ion removal performance with an increase in the surface area, and the cost for the lead adsorption is much lower than that of the conventional commercialized adsorbent. Therefore, it can be widely used as an economical adsorbent which can replace the conventional lead removing adsorbents.
