Kinetic adsorption of fluoride from an aqueous solution onto a dolomite sorbent

© 2016, Chulalongkorn University 1. All rights reserved. The adsorption of fluoride from an aqueous solution onto a dolomite sorbent was studied. The surface morphology of the dolomite sorbent was evaluated, and it was found to have an un-smooth porous structure. The point of zero charge (PZC), spec...

Wattanachira S. © 2016, Chulalongkorn University 1. All rights reserved. The adsorption of fluoride from an aqueous solution onto a dolomite sorbent was studied. The surface morphology of the dolomite sorbent was evaluated, and it was found to have an un-smooth porous structure. The point of zero charge (PZC), specific surface area, and average pore size of the dolomite were observed at approximate pH 8.0-9.5, 1.17 m 2 /g, and 105.7 Å, respectively. The major mineral components of the dolomite sorbent were dolomite, calcite, and quartz. From a kinetic adsorption test, the dolomite sorbent required 12 hours of contact time to reach equilibrium with a fluoride adsorption capacity of 0.000581 mM/g, and the kinetic adsorption fitted well with a pseudo-second order kinetic reaction with a rate constant of 21.07 g/mM·min. 2017-09-28T04:22:31Z 2017-09-28T04:22:31Z 2016-08-19 Journal 01258281 2-s2.0-84983455293 10.4186/ej.2016.20.3.1 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84983455293&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/41641
