Sažetak
A new rapid spectrophotometric method for the determination of Si is described. Chloranilic acid (CA) reacts with Si(IV) forming a complex, which is stable for several hours. The procedure is suitable for the determination of Si in the concentration range of 0.5-5.0 mmol/L at pH 1.25 measured at 370 nm. The relative standard deviation at the level of 1.0 mmol/L Si is +/-3.9%. Of the foreign ions investigated, Fe, Ti, Mo, and phosphate interfere significantly.
