Ultrasound waves are caused by oscillating molecular motions in a propagation medium. The waves have a very high frequency (20 kHz). Flow injection analysis is can analyze multiple samples, high accuracy, a very fast response time , modern technical devices that are small. This research intended to study the efficiency of ultrasound waves were determined total phenolic compounds in wastewater .Smart phone was used to investigate results and optimum conditions .The sample or standard phenol solution were injected into a carrier stream to react with 4-aminoantipyrine reagent then expose it to ultrasound waves (46 kHz) which was detected by spectrophotometer. A good linear calibration curve in the range of (250-2000 mg L-1 ) was obtained with regression equation ( y=0.0108 x + 0.3453) ,( R= 0.9989 ) . Results of the experiments showed that the ultrasonic method significantly decrease peak height after using ultrasound waves because of low measurement sensitivity due to effected on bonding process between total phenol compounds and the reagent, and the effect on the bonding of the components of the reagent .

“…Waves of ultrasound Cannot move through vacuums, and they reflect and are refracted like light waves (4) . In 1895, the year it was first mentioned, the phenomena of cavitation was first discovered (5) . Rapid decomposition, little secondary contamination, and ease of use are three benefits of ultrasonic technology that have garnered a lot of interest (6) .…”

Flow injection analysis is can analyze multiple samples, high accuracy, a very fast response time , modern technical devices that are small. This research intended to study the efficiency of ultrasound waves were determined total phenols in wastewater using Folin-Ciocalteu reagent in basic media .The sample or standard phenol solution were injected into a carrier stream to react with Folin-Ciocalteu reagent then expose it to ultrasound waves (46 kHz) which was detected by spectrophotometer at 765 nm. The calibration curve for this method was in the range of (250-2000 ppm ) .The average correlation coefficient was equal to(0.999) . Results of the experiments showed that the ultrasonic method significantly increase peak height after using ultrasound waves . The method was successfully applied for the determination of the total phenols in wastewater

“…The effects of sonication are linked to the cavitation phenomena, and they can be chemical, physical, mechanical, or optical. The first reference to the cavitation phenomena by Thornycroft and Barnaby dates from 1895 [11]. By the time Neppiras introduced the term “sonochemistry” in 1980 [12] and Makino et al showed the formation of radical species during the sonolysis of water in 1982 [13, 14], the research attraction of sonochemistry had increased dramatically.…”

A new field where the utilization of mechanochemistry can create new opportunities is materials chemistry, and, more interestingly, the synthesis of novel nanomaterials. Ball-milling procedures and ultrasonic techniques can be regarded as the most important mechanochemical synthetic tools, since they can act as attractive alternatives to the conventional methods. It is also feasible for the utilization of mechanochemical forces to act synergistically with the conventional synthesis (as a pre-treatment step, or simultaneously during the synthesis) in order to improve the synthetic process and/or the material’s desired features. The usage of ultrasound irradiation or ball-milling treatment is found to play a crucial role in controlling and enhancing the structural, morphological, optical, and surface chemistry features that are important for heterogeneous photocatalytic practices. The focus of this article is to collect all the available examples in which the utilization of sonochemistry or ball milling had unique effects as a synthesis tool towards zero- or one-dimensional nanostructures of a semiconductor which is assumed as a benchmark in photocatalysis, titanium dioxide.Graphical Abstract
