Abstract:

The problem of water pollution with organic compounds such as dyes is a big challenge. Many of water purification techniques were developed. The most technique that used is adsorption. In this paper, multiwall carbon nanotubes (MWNTs) were used as adsorbent for removal of scarlet red dye from industrial wastewater. So, in this paper the efficiency of MWNTs in removal of scarlet red dye under effect of pH = 7, concentration of MWNTs, concentration of dye, agitation time were studied. At equilibrium, the removal reaches 98% of dye. The kinetic studies were described by Langmuir model. To sum up, the results obtained showed that MWNTs had high efficiency in removal of dye from wastewater
