From Mining to High-Purity Metals: Efficient Ways for Elemental Analysis In terms of elemental analysis, the mining value chain has vastly different requirements. During early exploration and exploitation mostly major contents of elements in raw materials need to be determined. In later process stages – for example during production of high-purity metals and alloys – trace and ...
The fundamentals of the practice, called spectroscopy, involves deep analysis of specific light bands by breaking down the light source. For example, basic light analysis tools may break up light into red, blue and green colors, possibly using a prismatic feature. ...
Background A world leader in mining and metal refining has an in-house inorganic QA/Process Control laboratory which provides process control analysis, final product analysis and environmental analyses for the company’s refinery and supporting operations. The laboratory performs metals (trace and bulk) analysis on in-process samples from ...
The California Department of Toxic Substances Control (DTSC) has issued a draft of its Stage 1 Alternatives Analysis (AA) Guide. DTSC developed this guidance to help the regulated community conduct AA and regulatory requirements under the California Safer Consumer Products (SCP) program. ...
Carbon dioxide (CO2) is a major greenhouse gas responsible for global warming. This work aims to explore a cheap and easy way for CO2 adsorption from the atmosphere, by using an eggshell membrane. Eggshell membrane could be used up to four times with intermediate regeneration with acetic acid solution. Atomic absorption spectrophotometer (AAS) analysed the amount of CO2 adsorbed as equivalent ...
Metal mining activities often lead to plant and soil contamination in the surrounding environment. This article characterises the contaminated site and the effects of acidification and heavy metal pollution on two plant species: European birch and Norway spruce. The research was conducted in the surroundings of a former polymetalic mine near the town of Zlate Hory, Czech Republic. A by-product of ...
The application of radiochemical neutron activation analysis (RNAA) and atomic absorption spectrometry (AAS) is expected to aid in understanding and evaluating the effects of environmental pollution on the nutritional status of children already exposed to marginal malnutrition. ...
The advent of Inductively-Coupled Plasma (ICP) and Graphite Furnace AAS (GFAAS) brought the limits of analysis into the parts-per-billion (PPB) range for many matrices. ...
Of course, we do not compare XRF directly to AAS, but to the combination of the digestion method and AAS analysis. ...
