Summary: The azo dye Congo Red (CR) is commonly used to induce cell wall integrity stress in fungi. This toxic compound undergoes pH-dependent structural changes and can precipitate at low pH, affecting its toxicity. The growth of Aspergillus nidulans and Aspergillus niger was found to be affected by CR in a pH-dependent manner. Buffering the solutions at pH above 5 is recommended for studying the antifungal effect of CR, while lower pH is suggested for decolorization of CR solutions.

Summary: Poly-ferric-silicate-sulphate (PFSS), synthesized using a co-polymerization process, effectively removes diazo Congo red dye at lower coagulant dosages and a wider pH range. LC-MS analysis reveals a novel degradation pathway of the dye by PFSS, with azo bond cleavage confirmed by UV-Vis and FTIR spectra. Characterization using various techniques confirms PFSS as a polycrystalline material suitable for coagulation-flocculation, making it a highly efficient polymeric coagulant for dye removal from wastewater.

Summary: Every year, a large amount of water is polluted by various sources, with coal fly ash (CFA) being a major pollutant. CFA contains toxic metals that contaminate water bodies through contact with water or rain. Iron oxide nanoparticles (IONPs), recovered from waste like CFA, show promise for wastewater treatment due to their low cost, recyclable nature, and magnetic property. The synthesis of IONPs from CFA involves three steps: extraction of ferrous materials, acidic treatment, and precipitation of iron oxides. The synthesized IONPs have a particle size of 30-70 nm and a purity of 90-93%. They can efficiently remove heavy metals from wastewater, particularly Pb and Cr ions from CFA solutions, with removal efficiency ranging from 40-70%.
