Abstract: The main object of this study is to investigate the research trend in removal of dyes from waste water
by using adsorption technology for the past 16 years. Data are based on the online version of Science Citation
Index (SCI), Web of Science from 1993 to 2008 that covers all the articles published for the past 16 years in SCI
journals. Articles referring to dye adsorption were assessed by many aspects including model fitting the trend
of publication outputs during 1993-2008, distribution of author keywords and keyword plus analysis.
Distribution of articles based on subject categories and journals along with the country wise publications were
also studied. From the analysis of words appeared in the title and keywords, it can be concluded that “activated
carbon,” “biosorption,” “kinetics,” “Methylene blue,” and “isotherms” could be more popular words and the
new words like “photocatalytic degradation,” “photocatalysis,” “titanium dioxide,” and “oxidation” appeared
to be the new advanced techniques that are going to be adopted more in future studies. This method of
bibliometric analysis can help the relevant researchers to realize the panorama of globalized way of dye removal
from wastewater and establish the further research direction.
