The present investigation is an attempt on synthesising iron oxide nanoparticles through greener mode using the petal extracts of Hibiscus rosa-sinensis and utilising them as fortificants in wheat biscuits. Ferric and ferrous chloride at a concentration of 0.025 M and at a ratio of 2:1 was used as the metal precursors and the extract was served as the reducing agent. Synthesised iron oxide nanoparticles were characterised using UV-visible spectroscopy, X-ray diffraction (XRD), FTIR spectroscopy and scanning electron microscopy (SEM). The analyses confirmed that the formed particles were nano sized and the crystallite size was found to be 6.16 nm through XRD studies. The formed nanoparticles were observed from SEM analysis to be spinel shaped with an average particle size of 65 nm. Biscuits were fortified with iron oxide nanoparticles which were later studied for physical and proximate analyses. The inductively coupled plasma optical emission spectroscopy studies revealed that the iron content was higher in fortified biscuits than that in control. Microbial analysis for 30 days indicated that the fortified biscuits could have a longer shelf life. In brief, the first report on use of iron oxide nanoparticles successfully suggested that their use as fortificants in food and could be prescribed for malnourished, iron deficit or anaemic patients.

A photo-Fenton process using a local iron oxide as a natural catalyst was compared to Fenton and UV/H2O2 advanced oxidation processes for degrading crystal violet (CV) dye in aqueous solutions. The catalyst was characterized by transmission electron microscopy (TEM), energy dispersive X-ray microanalysis (EDX), Fourier transform infrared spectroscopy (FT-IR), Raman spectrum, X-ray diffraction (XRD), UV-vis spectroscopy, and Brunauer–Emmett–Teller (BET) analysis. The optical properties proved that the catalyst represents a good candidate for photocatalytic activity. The impact of different parameters (catalyst dose, initial CV concentration, initial H2O2 concentration, pH) on the photo-Fenton efficiency was evaluated. A photo-Fenton process operated under UVC light irradiation, at spontaneous pH, with 1.0 g/L of catalyst and 30 mg/L of H2O2 was the most effective process, resulting in 98% CV dye removal within 3 h. LC-MS and ion-chromatography techniques were used to identify demethylated organic intermediates during the process. Furthermore, a regeneration study of the catalyst showed its stability and reusability (after three treatment cycles, CV dye degradation decreased from 94% to 83%). Finally, the photo-Fenton process was tested in the treatment of real textile wastewater, and the effluent was found to be in compliance with standards for industrial wastewater disposal into sewerage.

Kajian Suseptibilitas Magnetik Bergantung Frekuensi terhadap Pasir Besi Kabupaten Takalar

2018

View full text Add to dashboard Cite

Telah dilakukan penelitian mengenai kajian suseptibilitas magnetik bergantung frekuensi terhadap pasi besi Kabupaten Takalar. Tujuan penelitian ini adalah mengidentifikasi mineral magnetik yang dominan berdasarkan data suseptibilitas magnetik dan menganalisis sumber mineral magnetik berdasarkan suseptibilitas magnetik bergantung frekuensi. Metode yang digunakan adalah metode magnetik batuan khususnya parameter suseptibilitas magnetik. Pengukuran dilakukan menggunakan alat Bartington MS2 Susceptibility Meter dilengkapi sensor MS2B yang bekerja pada frekuensi rendah (470 Hz) dan frekuensi tinggi (4700 Hz). Hasil penelitian mengindikasikan pasir besi mengandung mineral ferrimagnetik yaitu magnetite. Nilai suseptibilitas magnetik pada frekuensi rendah dan frekuensi tinggi identik serta persentase suseptibilitas magnetik bergantung frekuensi diperoleh kurang dari 2 % yang mengindikasikan pasir besi memiliki bulir magnetik multi domain (MD). Korelasi positif antara suseptibilitas magnetik pada frekuensi rendah dengan bergantung frekuensi mengindikasikan sumber mineral magnetik yang dominan berasal proses pedogenik yaitu pelapukan batuan gunung api.
