The findings from this work show the importance of incorporating photosensitizers such as phthalocyanines into Pluronic polymers micelles and making them water soluble and ultimately improving their photodynamic effect.]]> Wed 12 May 2021 14:58:28 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:4287 0.99. In the column experiment the highest loading capacity of Pt and Pd were 7.4 mg/g and 4.3 mg/g respectively on the nanofiber sorbent material based on ethylenediamine (EDA). The polystyrene and silica-based resins with triethylenetetramine (TETA) functionality (M-TETA and S-TETA) showed selectivity for platinum and palladium, respectively. Metal chlorido complexes loaded on the sorbent materials were recovered by using 3% m/v thiourea solution as teh eluting agent with quantitative desorption efficiency under the selected experimental conditions. The separation of platinum from palladium was partially achieved by selective stripping of PtCl₆²⁻ with 0.5 M of NaClO₄ in 1.0 M HCI with PdCl₄²⁻ was eluted with 0.5 M thiourea in 1.0 M HCI. The selectivity of the M-TETA and S-TETA sorbent materials was proved by column separation of platinum(IV) and palladium(II), respectively, from synthetic solutions containing iridium(IV) and rhodium(III). The loading capacity for platinum on M-TETA was 0.09 mg/g while it was 0.27 mg/g for palladium on S-TETA.]]> Thu 13 May 2021 07:36:09 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10377 Thu 13 May 2021 07:15:25 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10556 Thu 13 May 2021 06:25:31 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:36670 Thu 13 May 2021 00:48:57 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:20508 Thu 13 May 2021 00:32:04 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72822 Fri 31 May 2024 10:11:48 SAST ]]>
