Abstract

Graphene oxide coated wad as a new sorbent in fixed bed column for the removal of crystal violet from contaminated water AbstractAn efficient method was developed to fabricate graphene oxide coated cotton wad (GO/W) using self-assembly technique. GO/W could be used as an adsorbent material in remediation of environmental pollutants in a continuous packed bed column. 6 7 T The efficiency6 7 T 6 7 T of GO/W fixed bed column in removal of6 7 T crystal violet from aquatic environment 6 7 T was studied. 6 7 T The experimental breakthrough data were modeled using Thomas, Adams-Bohart and Yoon-Nelson models, and the column parameters for all these models were calculated. Increasing the effluent discharge rate and initial adsorbate concentration make the breakthrough and saturation points to be obtained faster and hence lower the adsorption capacity of column.

Temperature- and pH-Responsive Star Polymers as Nanocarriers with Potential for in Vivo Agrochemical Delivery

“…CV has been used as a fungicide for controlling plant diseases . With p K a values of 5.31 and 9.30, , CV is loaded into the star polymers at pH 6.5 via electrostatic attraction between positively charged amine groups in the CV and negatively charged carboxylate groups in the PAA blocks of the star polymers.…”
