| Abstract: | A method for simultaneous determination of Si, Mn, Fe, Ca, Mg, Al and Ti in Co rich crusts from the Pacific Ocean by ICP AES was developed. Samples were dissolved in mixed acid (HCl HNO 3 HF) and in a medium of 0.2 mol/L HF and 0.3 mol/L H 3BO 3.7 elements mentioned above were simultaneously determined by ICP AES. The method has been evaluated by analysis of oceanic polymetallic nodule reference material (GBW 07249). The results are in agreement with certified values with precision of <3.2% RSD ( n =6). The method has been applied to multi element analysis in Co rich crusts from the Pacific Ocean. |
