dc.description.abstract采用流动注射-氢化物发生-原子吸收光谱法研究纳米TiO2对Sn(Ⅱ)、Sn(Ⅳ)和二丁基锡(DBT)的吸附作用,探讨在不同pH值、吸附时间、试样浓度和试样体积下,不同用量的纳米TiO2的吸附效果以及试样的洗脱条件和效率。结果表明,Sn(Ⅱ)和Sn(Ⅳ)的浓度≤6.0μg/mL、体积≤500 mL、pH=3.0;DBT的浓度≤0.2μg/mL、体积≤50 mLp、H=4.0,30 mg纳米TiO2对Sn(Ⅱ)、Sn(Ⅳ)和DBT的吸附率≥90.0%。在25℃条件下,纳米TiO2对Sn(Ⅱ)、Sn(Ⅳ)和DBT的饱和吸附容量分别为23.6μg/mg、13.7μg/mg和0.628μg/mg,适用于无机锡和二丁基锡污染的吸附去除及对水中无机及丁基锡的定量富集。用4 mol/L HCl对吸附的Sn(Ⅱ)、Sn(Ⅳ)和DBT进行洗脱,洗脱率达到98%以上,可做为样品分析的前处理方法。 【英文摘要】 The adsorption behaviors about different species of tin(Sn(Ⅱ),Sn(Ⅳ),and dibutyltin) in water on nanosize TiO2 were studied.After adsorption or elution,the concentration of Sn(Ⅱ),Sn(Ⅳ) or dibutyltin(DBT) in filtrate or eluent was determined by flow injection-hydride generation-atomic adsorption spectrometry(FI-HG-AAS).The influenceable factors,including pH value,concentration of adsorbate,absorption time,sample concentration,sample volume and amount of adsorbent were studied.The adsorptive ratio of Sn(Ⅱ),Sn(...zh_CN
