Ultrasound assisted synthesis of praseodymium tungstate nanoparticles for the electrochemical detection of cardioselective β-blocker drug

Abstract This work reports the discrimination between the sonochemical and the magnetic stirring process of a conventional precipitation reaction. The praseodymium tungstate nanoparticles (PrWNP) used as a paradigm for this analysis. A 67.3 kJ of energy passed to the precipitated solution for 30 min sonication. Alongside this, the precipitated solution stirred for 2 hours at 700 rpm. The functional effects of these prepared materials have examined in the electrochemical determination of acebutolol (ACE). The high intense shock waves are successfully crystalized the PrWNP in the reaction mixture and produced the mixed phases of monoclinic and orthorhombic Pr2(WO4)3. However, the magnetic stirring process has failed to make such crystallinity. The obtained PrWNP is characterized by systematic investigations with spectroscopic techniques. Sonochemically furnished PrWNP is exhibited the high crystalline nanocube whereas stirring method has furnished the amorphous non-uniform distribution. Both PrWNP have examined in the electrochemical determination of ACE. The high electrocatalytic behavior obtained for the sonochemically prepared PrWNP. Although the amorphous material provides a high surface area, the crystalline material dominates the amorphous over the electrochemical behavior.
