Cupric oxalate is designated as a hazardous substance under section 311(b)(2)(A) of the Federal Water Pollution Control Act and further regulated by the Clean Water Act Amendments of 1977 and 1978. These regulations apply to discharges of this substance.

The first project focussed on fundamentals of FDFO process and its success precipitated an invitation to apply for an accelerated proposal for designing and fabricating a FDFO pilot scale desalination unit with a capacity of about 1 m3/day. Testing of the pilot scale scheme is in progress.

The following reagent and buffer stock solutions were prepared: AcetateKCl buffer (1 M KCl containing M equimolar sodium acetate/acetic acid), ammonia buffer (1 M NH 4 Cl, 2 M NH 3), M dimethylglyoxime (DMG), and 5 mM chloranilic acid.

• Decision Support Tools: Develop and implement, with users and partners, tools to apply weather, water, and climate information, including forecast uncertainty, into user decision processes and systems.

Virtual Lab at Amrita uses stateoftheart computer simulation technology to create real world environments and problem handling capabilities is required to bridge the gap between institutions (or industries) that retain the physical laboratory and distantly placed economically challenged educational institutions in areas such as Physics, Chemistry and Biotechnology.

try and gravimetry. Volumetric and gravimetric techniques are required to train students in accuracy and allow for highly critical assessments of results, consistent with the findings of Kratochvil (11). This approach matches the findings of a recent report on the important practical skills required of new chemistry graduates (12),

Water chemistry was characterized using direct water samples from springs, sinking streams, surface water, and a residential well in the project area that were analyzed for anions. Anion concentrations were determined using a Thermo Dionex ICS5000+ Ion Chromatography System.

The Department may issue a determination that the material continues to meet the relevant criteria of the variance or may require the facility to reapply for the variance. (d) Variances shall be effective for a fixed term not to exceed ten years. No later than six months prior to the end of this term, facilities must reapply for a variance.

The presumption does apply to metalworking oils/fluids if such oils/fluids are recycled in any other manner, or disposed. (B) The rebuttable presumption does not apply to used oils contaminated with chlorofluorocarbons (CFCs) removed from refrigeration units where the CFCs are destined for reclamation.

Ion beam analysis has been applied to a variety of problems involving the diffusion of small molecules in polymeric matrices. Energy loss techniques have been used .

Underground brines of Salar de Atacama, Chile contain the highest concentrations of potassium and lithium ever known. Their mining consists of pumping followed by evaporation in evaporation ponds ...

Separation, concentration and leaching processes involve several operations such as screening, classification, solidliquid separations, gravimetry, flotation, and pregnant liquid solution treatment. Sometime, the selection, design and operation of any process are complex and needs a special study.
