S. S. R. M. D. H. R. Wijesekara,Sonia Mayakaduwa,A. R. Siriwardana,Nalin de Silva,B. F. A. Basnayake,Ken Kawamoto,Meththika Vithanage +6 more
TL;DR: In this article, the characterization of leachate generated from Gohagoda dumpsite in Kandy, Sri Lanka, assessment of its spatial and temporal variations, and identification of subsurface canals and perched water bodies in the wetland system affected by the leachates flow.
Journal ArticleDOI
Organic-coated nanoparticulate zero valent iron for remediation of chemical oxygen demand (COD) and dissolved metals from tropical landfill leachate.
TL;DR: The use of nanoparticulate zero valent iron (NZVI) in the treatment of inorganic contaminants in landfill leachate and polluted plumes has been the subject of many studies, especially in temperate, developed countries as mentioned in this paper.
Journal ArticleDOI
Adsorption of Cd(II) and Pb(II) onto Humic Acid–Treated Coconut (Cocos nucifera) Husk
B. G. N. Sewwandi,Meththika Vithanage,S. S. R. M. D. H. R. Wijesekara,M. I. M. Mowjood,Shoichiro Hamamoto,Ken Kawamoto +5 more
TL;DR: In this paper, the adsorption of Cd2+ and Pb2+ by raw and sieved coconut husk (CH) from Sri Lanka was treated with humic acid to use as the adsorbent in laboratory experiments.
Book ChapterDOI
