Low cost treatment of wastewater containing mercury salts
Removal of mercury from wastewater is of considerable significance from an environmental point of view. Treatment of wastewater containing mercury salts has been carried out with the help of modified fly-ash bed. The preparation of the bed material has been described. The effects of different parameters such as pH, exchange capacity and the presence of other constituents have been studied. ...

Surfactant enhanced in-situ remediation of DNAPL impacted soil and groundwater - Montreal refinery
Abstract A Montreal chemical refinery reduced the dichlorobenzene and other dense non-aqueous phase liquid (DNAPL) impacts on the soil and groundwater where a railway line is adjacent to an above ground storage tank farm. Ivey-sol® surfactant mixtures were injected three times during a two week pilot test, into a series of in-situ wells. The soil and groundwater matrix experienced an induced ...

Determination of trace amounts of mercury (II) by catalytic kinetic method in environmental samples
A highly selective and sensitive, spectrophotometric method is developed for the determination of Mercury(II) in environmental waters samples, based on indicator reaction of potassium hexacyanoferrate(II) and 2-methylpyrazine (2-Mepz), catalysed by Hg(II). The reaction was monitored spectrophotometrically at pH = 3.50 ± 0.02 and 25.0 ± 0.1°C by measuring the change in absorbance over time at 447 ...

Mercury mobility and availability in highly contaminated solid wastes from a chlor-alkali plant
This article suggests an approach of sustainable development in Cuba based on the environmental impact assessment of mercurial sludge generated by a chlor-alkali Cuban plant. It consists of a study of mercury mobility and availability in the sludge samples using sequential extraction procedure. High values of total mercury content (2320 ± 40 mg/kg) in the sludge sample as well as in the ...
