A flow-sonochemiluminescence (SCL) method that offers a fast and simple alternative to the antioxidant capacity analysis is described. Reactive oxygen species (ROS) is generated reagentlessly and in situ in pH 7.4 phosphate buffer saline by ultrasound irradiating. Luminol reacts with the ROS to give SCL. The presence of antioxidant quenches the ROS, which in turn quenches the SCL. By quantifying SCL...
Sonoluminescence can photoexcite fluorescent solutes yielding sonophotoluminescence (SPL). The possibility of applying multibubble sonophotoluminescence (MBSPL) for chemical quantitative analysis is examined in this work. Special devices for MBSPL quantitative detection are designed and fabricated. Calcium contents in pharmaceutical samples are selected to verify the proposed MBSPL analysis. Coupled...
