Gallium-based room-temperature liquid metals possess extremely valuable properties, such as low toxicity, low vapor pressure, and high thermal and electrical conductivity enabling them to become suitable substitutes for mercury and beyond in wide range of applications. When exposed to air, a native oxide layer forms on the surface of gallium-based liquid metals which mechanically stabilizes the...

A simple, rapid procedure for the determination of organic mercury in sediments, plants and fish tissues has been developed and validated. Extraction and separation of organic mercury compounds from the sample matrix was achieved by an established procedure based on an acid leaching of the sample (H2SO4/KBr/CuSO4), followed by extraction of the organic mercury halide with toluene and back-extra...

We summarized the mercury flow of mercury-containing products from their manufacture to their disposal in Japan and discussed the current management of mercury-containing hazardous household waste (HHW). The mercury flow originating from these products was estimated to be about 10-20 tonnes annually, about 5 tonnes of which was attributable to fluorescent lamps, the major mercury-containing pro...

The magnetic susceptibility of liquid-mercury-based alloys containing5,8,15 and Bat .% Na is investigated. Changes in the paramagneric contribution of the conduction electrons are discussed in terms of negative excess molar volume. The anomalous variation of the total magnetic susceptibility with the composition is analysed. The occurrence of Hg, units appears to be corroborated from the compos...

BACKGROUND Dental practices use disinfectants or line cleaners to flush dental unit wastewater lines to minimize odor generation, remove solid waste particles and remove biofilms in dental unit water lines (DUWLs). METHODS The authors evaluated 47 disinfectants or line cleaners for their potential to release mercury from amalgam waste. They prepared each product concentration according to the...

Mercury is also called “air raksa” or hydrargyrum which a chemical element with the symbol Hg and belongs to heavy metal group liquid form silvery color. that harmful skin when added cosmetics, especially creams on face, even in small concentrations because it toxic. Identification of laboratory using thin layer chromatography method help ultra violet light causes medical personnel be vulnerabl...

in this work, all-solid-state potentiometric pvc membrane sensor was introduced for fast andsimple monitoring of mercury ions in waste water samples. the all solid sate electrode is made based on aconductive composite of graphite, reduced graphene oxide, epoxy resin on a copper wire. a thin layer pvcmembrane is then coated on the surface of the new conducting transducer. pvc membrane is compose...

Abstract Gold mining activities influence the environment, mainly aquatic due to heavy metal and mercury detected in settling pond river waters. Based on laboratory analysis, it is known that Mercury concentrations water of inlet, transition, outlet zones respectively are 0.075 mg/L, 0.042 0.027 mg/L. These shown concentration was not passed Government Regulation Minister Environment No. 202 ye...
