Abstract

The solution of Na2CO3 was used as extraction liquid, silicon molybdenum blue method and two antipyrine methane method were adopted for the determination of silicon and titanium in reservoir sediments. The Si/Ti ratio was obtained through the formula: WBSi = WSi – K(WSi/WTi) × WTi and adjusted by non-biologic silica correction. The optimum experimental conditions and data analysis methods for corrected biologic silica were acquired, which showed effectiveness in realizing the measurement of sheer biogenic silica overcoming the interference of abiotic silica.
