Journal ArticleDOI
Sorption characteristics of peat from Brunei Darussalam for the removal of rhodamine B dye from aqueous solution: adsorption isotherms, thermodynamics, kinetics and regeneration studies
TL;DR: In this article, the effects of contact time, settling time and pH were studied to obtain the optimum conditions for adsorption studies and the Sips isotherm was found to be the best fit model.
Journal ArticleDOI
Use pattern of pesticides and their predicted mobility into shallow groundwater and surface water bodies of paddy lands in Mahaweli river basin in Sri Lanka.
TL;DR: Expected pesticide residue levels in both surface and groundwater were predicted to remain below the USEPA health advisory levels, except for carbofuran, indicating that pesticide pollution is unlikely to exceed the available health guidelines in the Mahaweli river basin in Sri Lanka.
Journal ArticleDOI
Biosorption and Desorption of Lead(II) by Hydrilla verticillata
P. K. Dileepa Chathuranga,D. M. R. E. A. Dissanayake,Namal Priyantha,Sithy S. Iqbal,M.C.M. Iqbal +4 more
TL;DR: The potential of nonliving biomass of Hydrilla verticillata to adsorb Pb(II) from an aqueous solution containing very low concentrations of Pb (II) was determined in this article.
Journal ArticleDOI
Artocarpus camansi Blanco (Breadnut) core as low-cost adsorbent for the removal of methylene blue: equilibrium, thermodynamics, and kinetics studies
TL;DR: In this article, the adsorption characteristics of methylene blue (MB) on the core of breadnut, Artocarpus camansi Blanco, were investigated, and the results showed that the MB removal process was both spontaneous and exothermic.
Journal ArticleDOI
Isotherm and kinetic study on Ni(II) and Pb(II) biosorption by the fern Asplenium nidus L.
D.M.R.E.A. Dissanayake,D.M.R.E.A. Dissanayake,W. M. K. E. H. Wijesinghe,W. M. K. E. H. Wijesinghe,S. S. Iqbal,Namal Priyantha,M.C.M. Iqbal +6 more
TL;DR: In this article, the extent of biosorption of Pb(II) and Ni(II), by dried leaves of the fern Asplenium nidus depends on experimental conditions, such as initial pH, initial concentration, contact time and shaking speed.
