| Abstract: | An ammonium phosphomolybdate volumetric method for determination of phosphorus pentoxide in phosphoric acid impregnated clay brick was developed. The proposed method was improved by the national standard method.. Effects of experimental conditions on determination results were discussed, and accuracy and precision tests of the method were also studied. The results indicated that the method was reliable and the obtained results were stable with good reproducibility. |
