“…Table 9 underlines several research attempts using different nanomaterial-based sorbents to develop 99 Mo/ 99m Tc generator systems (Chakravarty et al, 2008(Chakravarty et al, , 2010c(Chakravarty et al, , 2012a(Chakravarty et al, , 2013Fasih et al, 2016;Nawar, 2021). It can be observed that the new sorbents exhibit a much higher sorption capacity for 99 Mo compared to the commercially used alumina.…”

The continuing rapid expansion of 99mTc diagnostic agents always calls for scaling up 99mTc production to cover increasing clinical demand. Nevertheless, 99mTc availability depends mainly on the fission-produced 99Mo supply. This supply is seriously influenced during renewed emergency periods, such as the past 99Mo production crisis or the current COVID-19 pandemic. Consequently, these interruptions have promoted the need for 99mTc production through alternative strategies capable of providing clinical-grade 99mTc with high purity. In the light of this context, this review illustrates diverse production routes that either have commercially been used or new strategies that offer potential solutions to promote a rapid production growth of 99mTc. These techniques have been selected, highlighted, and evaluated to imply their impact on developing 99mTc production. Furthermore, their advantages and limitations, current situation, and long-term perspective were also discussed. It appears that, on the one hand, careful attention needs to be devoted to enhancing the 99Mo economy. It can be achieved by utilizing 98Mo neutron activation in commercial nuclear power reactors and using accelerator-based 99Mo production, especially the photonuclear transmutation strategy. On the other hand, more research efforts should be devoted to widening the utility of 99Mo/99mTc generators, which incorporate nanomaterial-based sorbents and promote their development, validation, and full automization in the near future. These strategies are expected to play a vital role in providing sufficient clinical-grade 99mTc, resulting in a reasonable cost per patient dose.

“…Titania or titanium dioxide (TiO 2 ) is become an effective sorbent with high sorption capacity capable for both cations and anions [ 17 ]. Due to its high surface homogeneity, TiO 2 has a high selectivity for a large variety of compounds and has shown potential applications in adsorption [ 17 , 18 ] and separation science [ 19 ]. Modification of metal oxide materials by the surfactant can also greatly improve their sorption ability for the target compounds [ 20 , 21 , 22 ].…”

In this work, the magnetic sorbents based on different surfactant-coupled titanium dioxide coated iron-aluminium mixed metal hydroxide were investigated as sorbent for extraction of bisphenol compounds. The structure, morphology, and magnetic property of the synthesized sorbents were investigated. The cetyltrimethylammonium bromide-titanium dioxide coated iron-aluminium mixed metal hydroxide (Fe-Al MMH@TiO 2 -CTAB) exhibited excellent extraction performance toward bisphenols and was selected as the sorbent for development of magnetic solid phase extraction (MSPE) method. The entire MSPE process was optimized, and the extract was analyzed by high performance liquid chromatography with photodiode array detector. The method provided wide linear calibration ranges for bisphenols between 0.3-6000 μg L À1 with maximum enrichment factors of 280. The limits of detection and limits of quantification were in the ranges of 0.08-0.3 and 0.3-1.0 μg L À1 , respectively. The proposed MSPE method was tested for determination of bisphenols in carbonated beverages. The studied carbonated beverages were mostly free of bisphenol contamination; however, BPS, BPA and BPB were detected in samples taken from defective cans. The relative recoveries ranging of 80.2-118.9% were obtained. The asprepared Fe-Al MMH@TiO 2 -CTAB sorbent provided high sorption capacities in the range of 2215-2451 mg kg À1 and could be a promising material for bisphenols in beverage samples.
