摘要
探讨了芦苇残体及腐化脱糖后对氟离子的吸附行为特征。比较芦苇残体经过腐化脱糖前后的根、茎、叶对其吸附量大小及其前后变化。实验表明,改性前后芦苇根的吸附量均大于芦苇茎和叶;原始样品茎吸附量大于叶,而腐化样品叶大于茎,且腐化后各组织吸附量增大了近10倍,远大于原始样品;脱糖腐化可以提高吸附量。
The adsorption behavior characteristics of fluoride ions by reed residues have been discussed.Comparing the adsorption capacities and changes of raw and desugared reed root,stem,and leaf,the experiment indicates that whether modified or not,the adsorption capacities by the reed roots are higher than the stems and leaves,and the adsorption capacity by the raw stem is higher than the raw leaf,while the modified samples are opposite. Further,the adsorption capacities of the modified samples are enlarged almost 10 times,much larger than the raw samples,the desugarization can improve the adsorption capacity.
