| Abstract: | Titanium Oxalate Spectrophotometry was used to determine the H2O2 concentration in O3/H2O2 advanced oxidation system.The influence of pH,O3/H2O2 molar ratio,titanium oxalate dosage and coloration period on H2O2 determination was investigated to find the optimal factors and the method reliability was testified by comparative and recovery of standard addition experiments.The results showed while pH=3.0,λ=385nm,dosage of titanium oxalate 2.5mmol·L-1 and coloration time 8min,the absorbance was linear correlation to H2O2 content during 0~45mg·L-1,moreover the O3/H2O2 molar ratio had no influence on it.The H2O2 recovery of standard addition ratio range of the Milli-Q water /H2O2 Milli-Q water/ H2O2/O3 system with Atrazine was from 95% to 105% and the potassium permanganate method was in agreement with the titanium oxalate method while in Milli-Q water/H2O2 system but deviated fairly in Milli-Q water/O3/H2O2 system,which suggested the Titanium oxalate method could be used to determine the H2O2 content changing in the O3/H2O2 advanced oxidation system. |
