The decoloration property of modified reed absorbent for alkaline fuchsine wastewater

摘要

The modified reed absorbent was obtained by the being treated process with NaOH solution. The decoloration property of modified reed for alkaline fuchsine was studied under different conditions. The effects of adsorbent dose, adsorption temperature, adsorption time and pH value on the decoloration property were investigated, and the optimal adsorption condition was gotten, the discoloration rate was above 95%. The adsorption isotherm was well represented by the Langmuir.
