Bismuth phosphomolybdate blue spectrophotometry has been widely used in the determination of phosphorus in steel, iron alloy and ore. According to the chemical principle of bismuth phosphomolybdate blue spectrophotometry, some conditions influencing analytical results were tested. The proposed method was applied to the determination of coke Phosphorus content, obtained satisfactory results. 1 Experimental part 1 1 Main instruments and reagents 72 Type 1 spectrophotometer (Shanghai Third Analytical Instrument Factory).
