The use of reed seed as adsorbent to remove methylene blue and congo red dyes from aqueous solution by adsorption

Abstract

The present study was conducted as an attempt to find and inexpensive novel adsorbent that can be used to get rid of the dangerous. Throughout the study the ability of reed seed to get rid of both Congo red and methylene blue dyes was estimated. The newly proposed adsorbent showed a very high removal efficiency (R%) for both dyes with removal percentage up to 99% for the congo red and up to 72% for the methylene blue dyes, respectively. The reed seed as adsorbent was highly efficient in the removal of the days at different concentrations (from 10 to 50 ppm) with R% range from 94 to 96 % for methylene blue and from 22 to 72 % for congo red, while the highest R% for methylene blue was 96 at pH 7, and it was 72% at pH 5 for the congo red.
