Remediation of methylene blue dye in aqueous solution using structurally diverse and porous In(III)chloride metalloporphyrins

Synthesis, characterization, and application of a zinc oxide–pyrrole–thiophene nanocomposite as an efficient adsorbent for the removal of tetracycline

“…17 Conclusively, increasing the adsorbent dosage increased the adsorption efficiency of tetracycline, but after reaching the optimum adsorbent dosage, the subsequent increase in dosage had little influence on the removal efficiency. 46…”

“…17 Conclusively, increasing the adsorbent dosage increased the adsorption efficiency of tetracycline, but after reaching the optimum adsorbent dosage, the subsequent increase in dosage had little influence on the removal efficiency. 46 Fig. 8(d) shows the impact of the stirring rate (50-300 rpm) on the removal % of TC at pH 6.9, adsorbent dosage of 1.2 g L À1 , and contact time of 150 min.…”

Sunlight-Driven Photocatalysis for a Set of 3D Metal–Porphyrin Frameworks Based on a Planar Tetracarboxylic Ligand and Lanthanide Ions

“…Specific studies have demonstrated that MPFs have been employed as photocatalytic systems for dye degradation and photodynamic therapy involving the generation of reactive oxygen species (ROS). − As a proof of concept, we analyzed the photocatalytic activity of selected Ln-TCPPs (Ln = Sm, Eu, Gd, Y, Er, and Yb) samples with methylene blue (MB) as a model of organic pollutant in an aqueous medium. , The typical MB absorption band, centered at 663 nm, was monitored to track the reaction progress. − Figure shows the time-resolved UV–vis absorption spectra of the Ln-TCPPs photocatalysts in the 350–750 nm range, registered up to 100 min of irradiation using a xenon lamp source. A continuous decrease in the absorption maximum is observed for Sm-TCPP and Y-TCPP , denoting the dye degradation.…”
