“…As a result, it can be assumed that the adsorption mechanism of SAA on PMK is similar because the functional groups are identical. As is known to all, physical interactions (the first three) are exothermic, while chemical reactions (the latter) are endothermic [ 35 , 37 , 38 ]. More phenylboronic acid groups are present in PMP, which indicates a larger percentage of chemical reactions.…”

Due to its success in treating cardio-cerebrovascular illnesses, salvianolic acid A (SAA) from Salvia miltiorrhiza is of major importance for effective acquisition. For the adsorption of salvianolic acid, cationic polyelectrolytes, and amino-terminated silane intercalated with phenylboronic-acid-functionalized montmorillonites, known as phenylboronic-acid-functionalized montmorillonites with PEI (PMP) and phenylboronic-acid-functionalized montmorillonites with KH550 (PMK), respectively, were produced. In this paper, detailed comparisons of the SAA adsorption performance and morphology of two adsorbents were performed. PMP showed a higher adsorption efficiency (>88%) over a wide pH range. PMK showed less pH-dependent SAA adsorption with a faster adsorption kinetic fitting in a pseudo-second-order model. For both PMP and PMK, the SAA adsorption processes were endothermic. Additionally, it was clearer how temperature affected PMP adsorption. PMK has a higher adsorption selectivity. This study demonstrates how the type of intercalator can be seen to have an impact on adsorption behavior through various structural variations and offers an alternative suggestion for establishing a dependable method for the synthesis of functional montmorillonite from the intercalator’s perspective.

ZusammenfassungUrbane blau-grüne Infrastrukturen (Gründächer, grüne Fassaden, Baumrigolen etc.) erbringen wichtige Ökosystemleistungen. Sie dienen als Retentionsflächen für Niederschlagswasser und ermöglichen damit ein integriertes Regenwassermanagement im urbanen Raum. Über die Beeinflussung des Strahlungshaushaltes und der Evapotranspiration können Temperaturen innerhalb von Gebäuden sowie deren lokales Mikroklima verändert werden. Darüber hinaus haben blau-grüne Infrastrukturen das Potenzial, die biologische Vielfalt zu unterstützen und Umweltschadstoffe aus urbanen Wasserkreisläufen zu entfernen. In diesem Beitrag wird die Forschung am UFZ zur Multifunktionalität der blau-grünen Infrastrukturen vorgestellt und dabei wird insbesondere auf die Ökosystemleistungen von Gründächern eingegangen.

“…For this phenomenon, we compared the total pore volumes in the sample and observed that the total average pore volume (0.79 m 3 ⋅g − 1 ) of the activated carbon in Shi et al [93] is about 50 % lower than that of this work. Furthermore, the surface chemistry caused by impurities on the biochar surface might have formed a more effective surface chemistry for ammonia adsorption [94] compared to activated carbon. From an application perspective, the percentage of ammonia removal of the MBC bio-absorbent is comparable to commercial ammonia removal resins such as Purolite C160H [95].…”
