  • Effects of pH and coexisting chemicals on photolysis of perfluorooctane sulfonate using an excited xenon dimer lamp

    Vacuum ultraviolet (VUV) photolysis at the wavelength of 172 nm in a sulfate solution was introduced as a more efficient process for perfluorooctane sulfonate (PFOS) degradation than ultraviolet (UV) photolysis at 254 nm. The effects of pH and coexisting chemicals on VUV photolysis under the coexistence of 100 mM sulfate were investigated. VUV irradiation successfully degraded PFOS, and the ...

  • Incandescent, Fluorescent, and Mercury

    In light of many countries legislating the retirement of Thomas Edison’s beloved incandescent lamps in favor of more energy efficient compact fluorescent lamps, it is important to reassure the consumer that this phase-out is both necessary and safe. In order to properly illuminate the concerns regarding compact fluorescent lamps one must first understand their predecessor the incandescent ...

  • Enhanced photobactericidal activity of ZnO nanorods modified by meso-tetrakis(4-sulfonatophenyl)porphyrin under visible LED lamp irradiation

    In this study, zinc oxide (ZnO) nanorods have been synthesized using a simple template-free precipitation technique and deposited on glass substrate. The meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS) has been synthesized and then immobilized on the surface of ZnO nanorods to prepare an organic/inorganic composite. The samples were characterized by various techniques such as X-ray diffraction, ...

  • 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 ...

  • 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 ...

  • Led fluorescent lamp to LED lighting is a form of " hype "

    Led lighting actual demand (consumer demand) that is rigid demand, is actually very small. Indoor lighting products world for a year is just over one hundred million dollars total demand only, but an investment in this country, at least 10 times higher than the actual demand. Final pay is often investors. In fact the demand for LED lighting is a major investment (rather mostly speculative) ...

  • Here is a quick way to cool your office and home using LEDs

    Ever wonder how much heat your lighting fixtures are giving off? Did you know excess heat produced by incandescent bulbs, lamps, and fixtures indoors can cause irritation, waste, and unsafe conditions in numerous applications. Instances of incandescent fixtures catching on fire, exploding, or causing strain on cooling units due to extreme levels of heat being emitted have been documented numerous ...

  • Climate action issues: Increase recycling rates, save the planet

    Evidence is mounting that climate change is real and impacting our planet right now. Last summer had many weather extremes: floods, fires, melting ice and feverish heat. These weather-related disasters fit patterns predicted by the World Meteorological Organization and the International Panel on Climate Change. These organizations predicted there would be “more frequent and more intense ...

  • Government to invest GBP£70m in green facilities

    The Mayor of London has announced the government's intentions to invest GBP£70 million in the development of low-carbon waste and recycling facilities in the capital. This could potentially create hundreds of jobs in engineering and construction, as several biomass, incineration sites and recycling centres for food and plants will be built; saving the capital millions of pounds, according ...

  • Photocatalytic hydrogen generation from water under visible light using core/shell nano-catalysts

    A microemulsion technique was employed to synthesize nano-sized photocatalysts with a core (CdS)/shell (ZnS) structure. The primary particles of the photocatalysts were around 10 nm, and the mean size of the catalyst clusters in water was about 100 nm. The band gaps of the catalysts ranged from 2.25 to 2.46 eV. The experiments of photocatalytic H2 generation showed that the catalysts ...

  • The Alamitos Barrier Recycled Water Project

    Groundwater pumping in the Los Alamitos, California area over the last century has caused groundwater levels to drop, allowing seawater to intrude into the local groundwater aquifer. To prevent additional infiltration by seawater, a coastline barrier of wells injecting fresh water has been in place since 1965. Until recently, imported potable drinking water was injected into the aquifer. However, ...
