Chemical and Mineralogical Characterization of Ghanaian Foundry Slags

Simultaneous Mineralogical Quantification and Chemical Characterization of Soil Clays

-A new chemical mass balance technique has been developed for simultaneous mineralogical quantification and chemical characterization of soil clays. The procedure includes separation of the whole clay (<2 ~tm fraction) into six particle size fractions (<0.02, <0.06, <0.2, 0.02-0.06, 0.06-0.2, and 0.22 um fractions), chemical analysis of the whole clay and each of the six fractions, and fitting ...

Investigation on Mineralogical and Chemical Characterization of Ilm

Surface samples have been collected from Kerala coast, Valapatanam-Azhikode deposit of northern Kerala coast. The average heavy minerals percentage shows 30.32 %. The heavy mineral assemblage of samples from area showed an appreciable percentage of opaque followed by sillimanite and zircon. The chemical analysis carried out for the present investigation, is detailed as Ferrian ilmenite. X-ray d...

Iron Foundry Slags for Removing Arsenic from Water

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...

Grey-iron foundry slags as reactive media for removing trichloroethylene from groundwater.

A feasibility study was conducted using slags from six grey-iron foundries to evaluate their potential as reactive media for permeable reactive barriers (PRBs) to remove aqueous trichloroethylene (TCE) from groundwater. Batch tests indicated that the slags exhibit varying degrees of reactivity ranging from nonreactive to reactivity comparable to that obtained with commercially available granula...
