Study on Adsorption Characteristics of Klebsiella Biological Adsorbent to Leaded Wastewater

Abstract:

A lead-resistant strains was isolated from activated sludge of the sewage treatment plant in Chenggong County, Kunming, which was identified as Klebsiella by 16 SrDNA. The wet microbial cells were used as adsorbent, we studied adsorption properties for water Pb (II) ions in water of sorbent. The results showed that when the adsorbent treated the waste water with Pb (II) ions, the pH was 5, the time was 60min, the temperature was 30°C, the equilibrium adsorption amount was 73.45mg/g; Adsorbent’s adsorption of Pb (II) ions can better fit Langmuir isotherm model. The FT-IR result presented that the main component of adsorbent was polysaccharide, the physical adsorption and chemisorption occurred between the adsorbent and the Pb (II) ions in the solution, adsorption mainly involved with hydroxyl functional groups, the amide group and the carboxyl group, etc.
