Study of performance amount of zeolite in the removal of Direct Blue 151 dye from aqueous solutions

摘要

In the case of Direct Blue 151 dye was observed causes numerous adverse environmental effects such as carcinogenesis, mutagenesis and chromosomal damage. Therefore the aim of this research is to investigate amount of dye analysis DB-151 by zeolite. Effect dye concentrations (25-75 mgL-1), contact time (5-15 min), adsorbent dosage (0.3-0. 9 g) and pH (4-10) were investigated in the removal of dye. The results show that the process of DB-151 has a high ability to remove of dye and dye degradation efficiency by increasing adsorbent dosage, pH and time increases and has inverse relationship with increasing concentration of dye.
