IntroductionThe strategy to Eliminate Yellow Fever Epidemics (EYE) is a global initiative that includes all countries with risk of yellow fever (YF) virus transmission. Of these, 40 countries (27 in Africa and 13 in the Americas) are considered high-risk and targeted for interventions to increas...

In this study, a series of polyaluminium chloride/papermaking sludge-based organic polymer (PAC-PSBF) composites with different PAC basicity and PAC/PSBF mass ratios were prepared from papermaking sludge. The basic properties of the aforementioned composites were characterized, and their floccul...

Reactive dyes are frequently applied in textile industries owing to varied color and texture. Treatment of such dye laden wastewater from textile industry is a major problem. Over the last few decades the most convenient removal mechanism adopted was adsorption using conventional adsorbents. Met...

Effluents from the paper printing and textile industries are often heavily contaminated with azo dyes. Azo dyes are difficult to oxidize biologically.
