“…As shown in the previous section, in ultrasound technology, HO • is generated during cavitation according to Eq. 15 (Muñoz-Calderón et al 2020 ) in the range of 20 kHz to 10 MHz, and increased reaction time results in the production of HO • but increases energy consumption. …”

“…The drug is a potential contaminant in aquatic systems that needs to be removed using the established economic and efficient method . There are several factors affecting the removal efficiency of the drug from contaminated water such as (a) the components (water and oil phases) of the nanoemulsion, (b) the physicochemical properties (viscosity, globular size, ferrous ions, hydrogen peroxide, and refractive index) of the nanoemulsion, (c) the degree of polluted water, (d) method efficiency, and (e) other factors (pH, UV frequency, reducing agent, microbial inhibition by antibiotics). From the literature, it was concluded that the percent removal efficiency (%RE) of macrolides was comparatively lower than that of fluoroquinolones and the %RE values of ERN were 74 and 79% in wastewater treatment plants in Beijing and the United Kingdom (and Australia), respectively. , The drug can be estimated using previously reported methods based on the physicochemical nature of the drug. , The selection of excipients was based on various factors such as (a) the solubility of the drug, (b) the hydrophilic–lipophilic balance (HLB) value of the excipient, (c) medium-chain triglycerides capable of self-emulsification after dispersion into water, (d) capability of forming an emulsion through self-emulsification into water and subsequent adsorption of the lipophilic drug, (e) safety and biocompatibility, and (f) cost-effectiveness and ease of access. Labrafil M 1944 CS (LabM) consists chemically of mono-, di-, and triglycerides and PEG-6 (MW 300) mono- and diesters of oleic acid (C18:1) (source: Gattefossé leaflet).…”

“…Various conventional methods (physical, chemical, and microbial) have been exploited to remove macrolide contaminants from wastewater obtained from different water resources. , These conventional methods are the least efficient (unable to remove contaminants completely from water), hectic, and costly; have a high probability of microbial growth; and are difficult to scale up for bulk cleaning . Moreover, photocatalytic degradation, Fenton reaction, UV light application, ultrasound (low frequency ultrasound ∼40 kHz), and adsorption (activated carbon) based methods are commonly used techniques for remove trace amounts of macrolides present in aquatic systems despite several limitations. Recently, we reported green nanoemulsions as nanocarriers for removing few macrolides and anti-tubercular pharmaceuticals (clarithromycin, azithromycin, and rifampicin) contaminating aqueous solutions. These nanoemulsions are isotropic, and thermodynamically stable, composed of water, lipid, surfactant and co-surfactant. ERN is a poorly water-soluble (0.15 mg/mL) drug as evidenced by its log P value (2.6–3.06).…”

“…Very recently, low frequency ultrasound (40 kHZ) with or without hydrogen peroxide in aqueous solution was used to remove AZM. Authors studied the effect of solution pH (3-9), Fe ion, and UV light for the removal of AZM from aqueous solution using ultrasound (Muñoz-Calderón, et al 2020). The test was conducted at laboratory using an aqueous solution (1 mg/L) for 1 h in a reaction volume of 300 mL.…”

“…The removal e ciency was greatly in uenced with the external operational parameters such as pH, ultrasound, presence of ferrous ion, hydrogen peroxide and UV light. However, the achieved %RE was approximately 50 % only (Muñoz-Calderón, et al 2020). Furthermore, macrolides (erythromycin, azithromycin and clarithromyci) removal e ciencies were relatively lower as compared to uoroquinolones (cipro oxacin, o oxacin and nor oxacin) from the in uent of sewage wastewater collected from different countries (Ghosh et al 2016).…”
