Using x-ray and FT-IR teqencue to study and comparative two methods of carbonate minerals removal
AbstractThe objective of this study was to obtain the of best method carbonate removal from soil without effect in mineralogical properties. Three soil treatments for soil high content in calcite (Tall Keef region).Were used HCl acid (0.2N), sodium acetate pH (5) treatment and control treatment were conducted compared with control treatment.Results showed Bulk X-ray and XRDclay mineral were that use of HCl acid Caused to removal all carbonate without the effecting in quality and quantity of minerals Comparison with first treatment that it was not great influence. The group of mineral were diagnosed for the three treatments by using the Bulk x-ray showed dominate quartz,calcite,palygorskite,feldspar and kaolinite respectively,while the XRD for clay realated the rule of chlorite, illite,semctite and kaolinite respectively,as for FT-IR appearance group are bands important (1450 )cm-1,which represents carbonate group (dolomite-calcite)and Disappearance with third treatment without second,therefore acetate method is considered inappropriate for measurements which means to remove the carbonate. Meaning that use of HCl acid (0.2), N is optimum method.
