主 题：biosorption Agaricus bisporus zinc ionexchange FT-1R isotherms
摘 要：Abstract Biosorption of Zn2＋ from aqueous solutions by biomass of Agaricus bisporus was investigated. The removal rates of Zn2＋ by A. parameters （e.g., solution pH, initial Zn2＋ concentration） were A. bisporus＇s biosorption by bisporus under different bio-sorbent dosage and studied. The inhibition of anionic ligands EDTA （Ethylene Diamine Tetraacetic Acid）, acetate and citrate） implied that EDTA and citrate might be used as eluting reagents. Regular and simultaneous solution pH change and light metal ions release after biosorption indicated that an ion exchange mechanism was involved. From FT-IR （Fourier Transform Infrared） spectroscopy, the main functional groups participated in biosorption were found. Biosorption of Znz＋ byd. bisporus could be well described by the Freundlich and Langmuir models. In conclusion, the biomass of A. bisporus showed high potential for the treatment of wastewater containing Zn2＋.
