Enhanced photo Fenton-like activity by effective and stable Al–Sm M-hexaferrite heterogenous catalyst magnetically detachable for methylene blue degradation

Nano-compositing technologies are getting enhanced attention due to unique catalytic and separation activity with advanced characteristics for dye wastewater treatment. In this study, novel easily separable Ba–Sr based Al–Sm substituted M-hexaferrites (BASF-NPs) were fabricated as a highly effective heterogenous photo-Fenton-like catalysts via sol-gel route. The analytical techniques were applied to investigate BASF-NPs characteristics such as TGA, XRD, FTIR, XPS, SEM/TEM/EDS, UV–Vis, BET and VSM analysis. The results revealed that all fabricated BASF-NPs showed excellent photo-Fenton-like catalytic performance towards Methylene Blue (MB) degradation. Virtually complete degradation of an initial 10 mg/L MB was achieved under optimal conditions (i.e. 16 mM H2O2 and 0.25 g/L BASF-NPs) within 140 min of UV-irradiated reaction time and followed pseudo-first order reaction kinetic at the rate of 6.514 × 10?2 min?1. Similar degradation trend was noticed at various pH levels (pH 3–12), signifying the efficiency of the NPs at wide pH range. Due to the intrinsic magnetic nature of BASF-NPs, it was readily recoverable by external magnetic field and exposed strong capacity for dye removal treatment. The photo-catalysts retained its performance after four consecutive cycles, indicating robust reusability and excellent stability.

Sulfonation of arylamines: Part 11 - Preparation and thermal decomposition of ring-substituted arylammonium hydrogen sulfates

Eight ring-substituted arylammonium hydrogen sulfates (RSAHS) have been prepared by reacting corresponding arylamine with excess of conc. H2SO4. Their thermal decomposition has been investigated by TG and DSC techniques. The decomposition pathways have also been suggested.
