“…The ultrasonic characterization for non-destructive testing and imaging usually employs a low power signal with frequency up to 70 MHz. By contrast, the power of order of 10 W is generally required in ultrasonic cleaning (Saikia et al, 2014) dyeing (Guesmi et al, 2013), food processing (Kentish, Feng, 2014), natural product extraction (Esclapez et al, 2011), microbial cell disruption (Borthwick et al, 2005), acoustic cavitation (Khmelev et al, 2015) and sonochemistry (Son et al, 2012). Moreover, applications of power exceeding 100 W are common in biodegradation (Zawieja, Wolny, 2011) and alloy treatment (Shao et al, 2012).…”

A sonoreactor was assembled with stacked lead zirconate titanate transducers. These transducers were attached on one side of a 10 × 10 × 10 cm 3 chamber and driven by an integrated circuit power amplifier. The impedance of the reactor was analyzed in order to determine a matching inductance. The electrical frequency could be varied from 20 to 50 kHz and the electrical output power was adjustable up to 65 W. The highest power was obtained in the case of resonance at 31 kHz and the maximum temperature at the heat sink of the amplifier rose to 42.0 • C. Both acoustic cavitation and mechanical effects could be utilized in this sonoreactor for a variety of purposes including sonochemical synthesis, ultrasonic cleaning and microbial cell disruption.

“…Recently, there is a rising interest in natural colorant as currently used synthetic dyes have been suspected to cause or promote undesirable effects on human health and dangerous risks to the environment [11,12]. Several techniques are used to enhance the uptake of natural colorant such as ultrasonic method [13], gamma radiation [14][15][16], plasma treatment [17,18], and UV-radiation technique [19].…”

Use of ultrasonic energy for enhancing the dyeing performances of polyamide fibers with olive vegetable water

et al. 2015

The present study reports the valorization of the olive vegetable water in natural dyeing. HPLC analysis of the phenolic extract obtained from the used olive vegetable water showed that the predominant flavonoid compounds were luteolin and apigenin. Hydroxytyrosol and various phenolic acids were also identified. This abundant waste was used as a possible dye bath for dyeing polyamide fabrics in conventional and ultrasonic techniques. It was found that these synthetic fibers possess high affinity to the olive vegetable water giving brownish shades with generally good fastness properties. Factors affecting the dyeing performances such as pH, temperature, and duration of the dyeing time were studied. Ultrasonic dyeing showed marked improvement in the dye uptake compared to the conventional heating. The results also showed that the use of this method enhanced some fastness properties compared to the conventional method. Moreover, it was found that using ultrasonic technique can reduce the concentration of polyphenols so that it reduced the chemical oxygen demand COD and biological oxygen demand BOD 5 better than conventional heating method.

“…These natural dyes are believed to be safe because of their non-toxic, noncarcinogenic, and biodegradable nature [2]. Their use is also on the rise because they offer diverse and unique shades on different textile fabrics and they are found to be UV protective, deodorizing, antifeedant, antimicrobial, and antioxidant [3,4].…”

The extraction of colorant from Tamarix aphylla (L.) Karst. leaves was optimized using response surface methodology (RSM). The combined effects of extraction conditions (sodium hydroxide concentration, sample weight, and extraction time and temperature) on the total phenolic content (TPC) and color yield (K/S) were studied using three-levels three-factors Box-Behnken design. The optimum conditions for dye extraction were found to be 0.25 mol/l, 65 min, 88 o C and 52.5 g/l for sodium hydroxide concentration, extraction time and temperature, and mass of the leaves powder respectively. The efficiency of extraction under these optimum conditions was found to be 1.12 g/l of phenolics and color yield equal to 11.20. Further, high-performance liquid chromatography analysis (HPLC) was used to identify the major phenolic compounds in the dye extract such as gallic acid, quercetin, luteolin, and kaempferon.
