Algae cells of wastewater containing heavy metal ions adsorption capacity

Algae adsorption area is large, and has good selectivity, its effect on the adsorption and enrichment of heavy metals have very strong, but in a shorter time to reach adsorption equilibrium. Its raw materials cheap easy, can screen is suitable for production material of algae as an adsorbent, artificial cultivation under the appropriate conditions. It is suitable for both water containing low concentration of metal ions, and is suitable for water containing high concentration of metal ions, does not produce secondary pollution. So the algae cell is excellent metal adsorption material.

LuoQiaoQi etc. [ 17] Using orthogonal experiment analysis of temperature and the concentration of heavy metal ions on the three kinds of algae powder ( Chlorella powder, spirulina powder, kelp powder) Adsorption of electroplating waste water of heavy metal ions ( Pb2 +, Cu2 + Zn2 +) Live, and compares the algae and algae powder on the adsorption of heavy metal ions. The results showed that the algae powder and live algae adsorption in order to eliminate the three kinds of heavy metal ions for Pb2 + & gt; Cu2+> Zn2 +; Three kinds of algae powder on the temperature of 40 ℃, the concentration of heavy metal ions is 6 tendency for L, achieves the maximum adsorption rate, each kind of algae powder for heavy metal ions adsorption rate was positively correlated with the concentration of heavy metal ions. Dead algae for heavy metal ions adsorption rate significantly greater than living algae, so dead algae using an edge in the industry.
