Description
Organoclays synthesised by the ion exchange of sodium in Wyoming Na-Montmorillonite (SWy-2-MMT) with three surfactants octadecyltrimethylammonium bromide (ODTMA) formula C21H46NBr b) didecyldimethylammonium bromide (DDDMA), formula C22H48BrN, and c) di(hydrogenated tallow)dimethylammonium chloride (tallow) were tested for hydrocarbon adsorption. Using diesel, hydraulic oil and engine oil an evaluation was made of the effectiveness of the sorbent materials for a range of hydrocarbon products that are likely to be involved in land-based oil spills. It was found that the hydrocarbon sorption capacity of the organo-clays depended upon the materials and surfactants used in the organoclay synthesis. Greater adsorption was obtained if the surfactant contained two or more hydrocarbon long chains. Extensive utilisation of chemometrics principally with the aid of MCDM methods, produced models which consistently ranked the organoclays well above any of the competitors including commercial benchmark materials. Thus the use of organo-clays for cleaning up oil spills is feasible due to its many desirable properties such as high hydrocarbon sorption and retention capacities, hydrophobicity. The negative effects of the use of organoclays for oil-spill cleanup are the cost, the biodegradability, and recyclability of the organo-clays
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads:
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
