Outline Chemical position analysis: to determine the kinds and the contents of the elements in a material. Qualitative and Quantitative Analysis. 武漢理工大學(xué)資環(huán)學(xué)院 管俊芳 12 describing the chemical position: Weight concentration: for solid, liquid General element %wt Micro Element: ug/g (g/t) (stands for ppm) 106 Supermicro : ng/g (ppb) 109 Hint Element: pg/g (ppt) 1012 Volume concentration: for liquid, gas General: mol/L Micro: mmol/L 武漢理工大學(xué)資環(huán)學(xué)院 管俊芳 13 Two kinds of position expression: a) For metal, single element material, sulfide, and some other materials that their ions are not oxygen. Expressing as Element content. For example: Iron(鋼材 ): Fe: %wt, C: %wt Pyrrhotite(磁黃鐵礦 ) (Fe1xS): Fe: %wt S: %wt Ni: %wt 武漢理工大學(xué)資環(huán)學(xué)院 管俊芳 14 b) For oxide(氧化物 ), Silicate(硅酸鹽 ), and some other materials that their ion is oxygen (carbonate碳酸鹽 , sulfate硫酸鹽 … ). When expressing their positions, generally as oxide types 武漢理工大學(xué)資環(huán)學(xué)院 管俊芳 15 For example: Orthoclass 鉀長(zhǎng)石 (KAlSi3O8): %wt SiO2 %wt %wt %wt %wt Fe2O3 %wt Calcite 方解石 (CaCO3): CaO %wt FeO %wt MgO %wt CO2 %wt 武漢理工大學(xué)資環(huán)學(xué)院 管俊芳 16 validating digits and their round … 2 validating digits after point: 3 digits: 4 no, 6 yes, 5 odd yes even no 2 digits:
