Multi walled carbon nanotubes as sorbent for removal of crystal violet.
Carbon nanotubes (CNTs) possess high surface active site to volume ratio as well as controlled pore size distribution that make them high profile material with an exceptional sorption capability and high sorption efficiency compared to conventional adsorbents. In the present paper, multi walled carbon nanotubes were synthesized by chemical vapor deposition (CVD) method and were further used for the removal of dye crystal violet. Microscopic and spectroscopic techniques were used for characterization. The systematic assessments of the pH and effect of adsorbent on different concentrations of dye with respect to contact time were examined. Langmuir and Temkin models were used to describe the isotherm studies.
