  • Sampling guidelines for handheld Raman measurements; what you need to know

    In recent years. Raman spectroscopy has seen increased adoption as the technique of choice for the rapid identification of materials; especially for raw material identification in the pharmaceutical industry, identification of controlled substances and explosives for security applications, polymer material identification for packaging and plastics recycling, and mineral and gemstone ...

  • Rapid high-performance sample digestion for ICP determination by ColdBlock™ digestion: part 2: gold determination in geological samples

    A procedure is described to tackle a weakness in laboratory analysis of geological materials, notably (1) systematic low gold recovery during wet sample dissolution using aqua regia, and (2) severe memory effect of gold during sample transportation and nebulization in conventional ICP/ICP-MS sample introduction systems. Modified aqua regia, in which hydrochloric acid is replaced by ...

  • Determination of distribution coefficient: a critical review

    Geomaterials (soils and rocks) exhibit peculiar physical, chemical, mineralogical and biological properties, which influence their interaction with the contaminant(s) to a great extent. This interaction can be quantified by employing a parameter 'Distribution coefficient', kd, which plays an important role for determining sorption and desorption characteristics of the ...

  • Building analytical competence for geoscience students through use of Raman spectroscopy

    Introduction: Traditionally, a geologist's analytical toolkit consisted of a hand lens, rock hammer, acid bottle, magnet, and perhaps a polarizing light microscope back in the laboratory. In geoscience professions, these tools are increasingly being supplemented by field and laboratory instrumentation that utilizes spectroscopy. The availability of newly-developed, lower-priced ...

  • MSITU Raman spectroscopy of cave minerals: an analytical tool compatible with the conservation of subterranean heritage

    Introduction: Up to 380 different minerals have been described in caves over the past century [1]. The presence of particular mineral phases has been used as indicators of specific paleoenvironmental conditions occurred in caves [2, 3]. On the other hand, processes involved in the genesis of some cave minerals have been proposed as potential analogs of minerogenetic mechanisms occurred during the ...

  • Environmental toxicity and radioactivity assessment of a titanium processing residue with potential for environmental use

    Thorough examination of the physico‐chemical characteristics of a Ti processing residue was undertaken including mineralogical, geochemical, and radiochemical characterisation, and an investigation of the environmental toxicity of softwater leachate generated from the residue. Concentrations of most metals measured in the leachate were low; thus, the residue is unlikely to leach high levels of ...

  • Chemical composition of groundwaters in the Hornsund region, southern Spitsbergen

    Chemical composition of groundwaters was investigated in the region of the Hornsund fjord (southern Spitsbergen). The investigations were conducted during polar expeditions organized by the University of Wroclaw in two summer seasons of 2003 and 2006. Three zones of groundwater circulation: suprapermafrost, intrapermafrost and subpermafrost, were identified in areas of perennial permafrost in ...

  • Treatment of salt affected soil in the oil field

    Soils, drill cuttings and other solid wastes which are exposed to high levels of salt through spillage from drilling and producing operations, pipe line breaks or leaks, become saturated with sodium. Although the EPA and the industry have demonstrated that the vast majority of such wastes are non-hazardous, in actuality, they have an adverse impact on the fertility of the soil. The degree of salt ...
