Fluorescent sporopollenin microcapsule modified by BODIPY for sensitive&selective recognition and efficient removal of Cu (II) from aqueous solution

Effects of a Cellulose Aerogel Template on the Preparation and Adsorption Properties of Coal Gangue-Based Multistage Porous ZSM−5

“…Table 6 shows the calculated values of ∆G • , ∆S • , and ∆H • . It can be concluded from Table 6 that ∆G • values were all in the range of −20 kJ/mol < ∆G • < 0 kJ/mol, indicating that the adsorption of MG by the molecular sieve was spontaneous physisorption [5]; ∆S • > 0 indicates the increase in chaos at the solid-liquid interface during adsorption [6]; ∆H • > 0 indicates that the process is an endothermic reaction, and raising the temperature is conducive to adsorption.…”

“…Gnanamoorthy et al [4] prepared CuNiO 2 and CuNiO 2 /rGO nanocomposites by a hydrothermal method, which showed good photocatalytic properties for methylene blue. Bilgic et al [5] successfully immobilized BODIP derivatives on APTES-modified sporopollenin microcapsules to obtain a fluorescent microcapsule sensor (Sp-APTES-monoBODIPY) for the selectivity and removal of Cu (II). The experimental results showed that Sp-APTES-monoBODIPY could be used as an ideal adsorbent and sensor material for Cu (II) with a maximum adsorption capacity of 25 mg/g by the complex quasi-secondary kinetic model and Langmuir model.…”

A selective bis‐thiophene chalcone‐based spectrofluorimetric sensor for Fe3+

“…High sensitivity, selectivity, and immediate response are advantages of cation-induced fluorescence-based chemosensors [5,6]. The development of highly selective colorimetric/fluorescent chemosensors for the identification of metal ions has gained considerable attention owing to their high sensitivity, selectivity, and quick response time when compared to conventional analytical techniques such as atomic absorption/emission spectrometry, voltammetric methods, and ion selective electrodes [7][8][9][10][11][12]. These classic analytical methods typically have several drawbacks, including time-consuming sample pretreatment procedures, pricey equipment, specialist people, and incapability for on-site measurement.…”
