The reaction between NaAsO2 and oxalic acid was studied by pH-metric and conductometric measurements, applying the methods of continual variation and pH-metric and conductometric titration. It was found that oxalic acid forms a complex anion of the type [AsOC2O4]-. The relative stability ...
The precursor solution was added with NaOH and HCl to adjust the pH value to approximately 4.05, 7.23, 11.31 before subjecting to the hydrothermal method. Fig. 17 shows the resulting morphology of NiMoO4 prepared at different pH: NiMo-4 (Fig. 17a–b, acidic, pH∼4), NiMo-7 (Fig. ...
In this context, the use of organic acids has been described as an effective way for avoiding acid pHs, since these form complexes with iron, which are more soluble as acidity decreases. Examples of organic ligands used to enhance the Fenton reaction are oxalic acid, citric acid, and oxalic...
