Mercury-based

Other organic mercurials similar in chemical stmcture to chlormerodrin are meraHuride/7(94-2(9-j5y, mercaptomerin/2 (922J-< 4-/7, and mersalyl [486-67-9]. Mercury-based diuretics (qv) are no longer in use.

Abstract The mercury-bearing lamps, towards the end-of-life, pose significant hazard potential due to the likely release of mercury. Though, these fluorescent lamps (FLs) release relatively less quantity of mercury when disposed as compared to other mercury-based products, they are still a concern due to the large and further growing number of FLs in service, particularly, in the domestic sector and then-fragile nature.

Aside from N2 adsorption, Kr or Ar adsorption can be used at low temperatures to determine low (<1 m2/g) surface areas [46], Chemically sensitive probes such as H2, Oz, or CO can also be employed to selectively measure surface areas of specific components of the catalyst (see below). Finally, mercury-based porosimeters, where the volume of the mercury incorporated into the pores is measured as a function of increasing (well above atmospheric) pressures, are sometimes used to determine the size of meso- and macropores [1]. By and large, the limitations of all of the above methods are that they only provide information on average pore volumes, and that they usually lack chemical sensitivity.

Large scale enrichment of lithium for thermonuclear uses took place at the Oak Ridge National Laboratory in the 1950 s. The enrichment primarily employed ion exchange between aqueous/organic solutions and amalgam, commonly mercury-based (Palko et al. 1976). Electrochemical separation has also been employed for such operations (Umeda et al. 2001). These practices have not been taken up in academic laboratories in the intervening years, partly as they tend to be most effective only with relatively pure starting materials, partly because of the difference in scales involved. Enrichment factors of Li of 1-7% are typical for these techniques (Symons 1985). 

A mercury-based maximum-minimum thermometer may be used to monitor temperatures during periods when the laboratory is not staffed. Large-volume refrigerators/freezers can be monitored with an upper- and lower-limit alarm system or a recording thermometer. Ah thermometers are to be calibrated with an appropriate National Inshtute of Standards and Technology (NIST) thermometer when put in service and every 6 mo thereafter.

Chlorine (from the Greek chloros for yellow-green ) is the most abundant halogen (0.19 w% of the earth s crust) and plays a key role in chemical processes. The chlor-alkali industry has been in operation since the 1890s and improvements in the technology are still important and noticeable, for example, the transition from the mercury-based technology to membrane cells [60]. Most chlorine produced today is used for the manufacture of polyvinyl chloride, chloroprene, chlorinated hydrocarbons, propylene oxide, in the pulp and paper industry, in water treatment, and in disinfection processes [61]. A summary of typical redox states of chlorine, standard potentials for acidic aqueous media, and applications is given in Scheme 2.

Although not in the strictest sense MCAs, the success of thiol-bearing polymers used by Bakir et al.22fi to suppress enterohepatic recirculation of methylmercury should be noted. The patients in this study were Iraqi farmers and other villagers who consumed seed grain which had been treated with a mercury-based fungicide. 

There has been a group of catalysts developed by polyurethane raw material suppliers with the polyurethane market in mind. Mercury-based catalysts, because of their toxicity, have been banned in some countries or severe restrictions placed on their use. Bismuth-based catalysts are recommended in their place. 

These methods use either a gold- or a mercury-based electrode.64 65 Despite past problems with determining inorganic arsenic species, Salaiin et al65 showed that As(III) can be determined by ASV using a gold microwire electrode at any pH, including the neutral pH typical of natural waters, whereas As(V) requires acidification to pH 1. Detection limits with this microelectrode are 0.2 nM As(III) at pH 8 and 0.3 nM combined arsenic (III + V) at pH 1 with a 30-s deposition time (Table 7.2). Additionally, copper is codetermined with this technique.

Bubble electrodes — Mercury electrodes constructed in such a way that an electrolyte solution is entering a mercury-filled vessel through one or many small orifices in the bottom (cf. Fig. 1). The solution bubbles grow and will finally ascend in the mercury. The counter and the reference electrode have to be situated in the tubing fed to the orifice. Bubble electrodes have been developed as flow-through detectors for HPLC and FIA [i-iii,vi], as electrodes to generate ESR-active species [iii-iv], for - tensammetry [vii], and for electrosynthesis [v]. The fact that they are mercury based impeded further developments of this electrode type.
