摘要
生物质灰由于具有较大的比表面积而成为常见的废弃物吸附材料,探究其对阴离子染料,活性蓝171、活性红23和酸性黑1,脱色能力。探究发现生物质灰渣对染料的吸附为物理吸附和化学吸附并存,在弱碱性环境下,生物质灰具有更高的脱色能力;并且染料的脱色率随染料初始浓度的增大而减小;25 min时达到平衡。
Due to high surface areas,biomass ash was regarded as new absorbent.It was used as adsorbent to investigate its de-colorization ability for anionic dyes,reactive blue 171,reactive red 23 and acid dye 1.It was found that the adsorption of dyes was a physical-chemical process.The biomass ash had a higher de-colorization for these dyes in alkaline solution.The de-colorization rate of these dyes decreased with the increase of the initial dye concentration.The adsorption equilibrium reached at 25 min.
