Efficient Removal of Toxic Bromothymol Blue and Methylene Blue from Wastewater by Polyvinyl Alcohol

Removal of bromothymol blue (BTB) and methylene blue (MB) from wastewater using polyvinyl alcohol (PVA) has been elucidated in the present work.PVA exhibited high adsorption capacity and more active sites for the highly efficient removal of these toxic dyes. The impact of several variables such as c...
