Abstract

Research on sonoluminescence spectroscopy was continued with a focus on determining the content of the main substance in natural underground brines and technological solutions with high salt concentrations (350-1000 g·dm^-3) using high-frequency ultrasound (44-50 MHz) to initiate sonoluminescence. The influence of the initiating ultrasound frequency on the sonoluminescence intensity of CsCl, LiCl, and NaCl was determined. The maximum sonoluminescence intensity for alkali metal chlorides was achieved at an ultrasound frequency of 48-49 MHz and an intensity of 32 W·cm^-2.A method for determining Cs, Li, and Na content in highly concentrated technological solutions using high-frequency ultrasound to initiate sonoluminescence was developed. The method's validity was verified by analyzing the same samples using sonoluminescence spectroscopy with low- and mid-frequency ultrasound initiation.The simultaneous effect of high-frequency (45-50 MHz) and low-frequency (18-23 kHz) ultrasound in determining macroimpurities (KCl and LiCl) in NaCl brines using sonoluminescence spectroscopy was studied.When using the simultaneous action of high-frequency (44-50 MHz) and low-frequency ultrasound (18-23 kHz), the lower limit of determination of KCl and LiCl content in brines decreases by 12-15 times compared to the use of ultrahigh and low-frequency ultrasound and amounts to 0.007 and 0.008 g·dm^-3, respectively. The best results were obtained with the simultaneous effect of high-frequency ultrasound of 47-48 MHz with an intensity of 29-30 W cm^-2 and low-frequency ultrasound of 19-22 kHz with an intensity of 1.3-1.5 W cm^-2.

EXPRESS：高频超声及高低频超声同时作用在声致发光光谱中的应用。

继续开展声致发光光谱研究，重点研究天然地下盐水中主要物质的含量和高盐浓度（350-1000 g·dm - 3）技术溶液（44-50 MHz）的声致发光技术。测定了引发超声频率对CsCl、LiCl和NaCl声致发光强度的影响。在48 ~ 49 MHz的超声频率下，碱金属氯化物的声致发光强度达到32 W·cm⁻2。建立了用高频超声引发声致发光法测定高浓度工艺溶液中Cs、Li、Na含量的方法。通过对同一样品进行低频和中频超声触发声致发光光谱分析，验证了该方法的有效性。研究了高频（45 ~ 50 MHz）和低频（18 ~ 23 kHz）超声同时测定NaCl盐水中微量杂质（KCl和LiCl）的效果。采用高频（44 ~ 50 MHz）和低频超声（18 ~ 23 kHz）同时作用时，卤水中KCl和LiCl含量的测定下限分别为0.007和0.008 g·dm-3，比超高频和低频超声降低了12 ~ 15倍。高频超声47 ~ 48 MHz、强度29 ~ 30 W cm-2和低频超声19 ~ 22 kHz、强度1.3 ~ 1.5 W cm-2同时作用效果最佳。
