SHEN Shi-de1,XU Juan2(1.Department of Architectural Equipment and Environmental Engineering,Xuzhou Institute of Architectural Technology,Xuzhou 221116,China;2.Ningbo Haiyan Environmental Protection Engineering Co. Ltd,Ningbo 315000,China)  
Grapefruit husk which abundantly contains cellulose,lignin and polysaccharide can chelate with heavy metals. Grapefruit husk peel as agricultural and living waste can be used as heavy metal adsorbent. NaOH-modified grapefruit husk powder was used as adsorbent to remove Cu(Ⅱ) and Zn(Ⅱ) ions in aqueous solution. Affecting factors on the adsorption of Cu(Ⅱ) and Zn(Ⅱ) ions from aqueous solution on NaOH-modified grapefruit husk powder including pH,shaking time,NaOH-modified grapefruit husk powder dosage,initial concentration of Cu(Ⅱ) and Zn(Ⅱ) ions were investigated. Adsorption isotherms were determined,isothermal adsorption law and adsorption kinetics was also discussed. Results showed that the factors enumerated above have definite influence on adsorption of Cu(Ⅱ) and Zn(Ⅱ) ions onto NaOH-modified grapefruit husk powder. Suitable conditions for adsorption of Cu(Ⅱ) were as pH 5.4~5.5,shaking time 10min,NaOH-modified grapefruit husk powder dosage 0.2g/100mL and initial concentration of Cu(Ⅱ) 20~80mg/L. Under the suitable conditions,removal rate of Cu(Ⅱ) can reach more than 95%. Suitable conditions for the adsorption of Zn(Ⅱ) were as pH 5.5~5.6,shaking time 60min,NaOH-modified grapefruit husk powder dosage 0.4g/100mL and initial concentration of Zn(Ⅱ) no more than 80mg/L. Under the suitable conditions,removal rate of Zn(Ⅱ) can reach more than 90%. Isothermal adsorption can be described well by Freundlich and Langmuir models. Adsorption appeared monomolecular layer and adsorption performance was favorable,with Cu(Ⅱ) and Zn(Ⅱ) ions easy to be adsorbed. Adsorption kinetics law conformed to pseudo first order model,pseudo second order model and Elovich equation.
