In the method, palladium oxide hydrate (PdO·H2O) nanoparticles (NPs) with high dispersion is obtained easily by adjusting solution pH in the presence of 1,4-butylenediphosphonic acid (H2O3P- CH2 4-PO3H2, BDPA).
The morphology and nanostructure of HC/MnO2 composites can be tuned by adjusting solution temperature (30, 60, and 90 °C).
The appropriate amount of humic acid was first dissolved into 60 mL of 0.05 M NaOH, followed by adjusting solution pH to 7.50 with 1.0 M HCl.
To analyze the interaction of aerobic granular sludge with BDE-209, experiments were carried out by adjusting solution pH, ionic strength, sludge dosage, initial BDE-209 concentration, and temperature in a batch mode for a period of 24 hours.
Because the mechanism of QD fluorescence sensing for Mn2+ is strongly pH dependent, where the sensing of Cu2+ is less pH sensitive, a recognizable detection of the two ions is possible by adjusting solution pH.
The pH of the experimental solution was adjusted, solution thoroughly mixed, and the measurements were repeated for several pH steps.
MACS and ADE are run in parallel with adjusting their solutions in search of a better solution.
Prior tests showed that adjusting the solution pH without first using Chelex caused P to precipitate from solution with cations.
By adjusting the solution pH, keratin can be used as polycation or polyanion.
The contact time was experimentally set by adjusting the solution flow rate, and was estimated by computational fluid dynamics modeling.
By adjusting the solution to insulin's isoelectric point, insulin of much greater purity could be obtained [ 20].
