Mercury adsorption-desorption and transport in soils
Kinetic sorption and column miscible displacement transport experiments were performed to quantify the extent of retention/release and the mobility of mercury in different soils. Results indicated that adsorption of mercury was rapid and highly nonlinear with sorption capacities having the following sequence: Sharkey clay > Olivier loam > Windsor sand. Mercury adsorption by all soils was strongly ...

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. ...

Characterisation of waste fluorescent lamps to investigate their potential recovery in Turkey
The investigations in this study were performed on two types of waste linear (tubular) T8 and T12 lamps, which are mostly used in Turkey. Total average value of the mercury mass for the T8 and T12 lamps were calculated to be about 6 mg and 12 mg per lamp, respectively. SEM–EDX elemental analysis showed that approximately 52% of hosphor powders of waste T8 and T12 lamps was measured as calcium ...

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 ...

Monitoring stack gas emissions of volatile trace elements, sulphur dioxide and pm10 particulates from coal-fired stoker systems
ABSTRACT A good deal of industrial coal combustion in New Zealand uses low ash highly alkaline subbituminous coals on stoker type units for raising process heat - substantially different coals, conditions and requirements for those most commonly used globally. Emissions control is typically by inertial grit arrestors (multicyclones). Emissions of interest include levels of toxic trace volatile ...

Fluorescent lamps recycling - Case Study
The fluorescent lamps recycling plant was designed for a Taiwanese recycling company. The task was to develop a treatment plant which achieves a high recycling quota while keeping the investment level moderately low. This was achieved by combining several specially developed technologies. These technologies include a high efficient shredder-sieving system, the closed-loop washing unit, an ...

Mercury – The Facts, Myths and Clean Up Tips!
Mercury, the facts. Mercury is an element (Hg on the periodic table) found naturally in the environment. Mercury emissions can come from both natural and man-made sources. It is commonly used in mercury arc lamps for UV curing, however this is a very minimal amount (as little as 5mg) and is used in the lamp to increase the voltage. Due to the harmful effects of Mercury, many ‘Mercury ...

Why Rare Earth Recycling is Rare (and What can We Do About it)
Earbuds, touch screens, CFLs with a warm glow, rechargeable batteries and power windows: Most of us take these things for granted. When we do, we also take for granted a group of elements called rare earth metals, whose special electronic and magnetic properties make them a key component of many 21st century technologies. These 17 elements are actually plentiful enough — you probably have ...
