    Biodegradation of Crystal Violet by Ascomycetous Fungi Isolated from Local Dump Sites: An Approach for Potential Mycoremediation of Textile Dyes
    (Department of Applied Sciences. Faculty of Humanities and Sciences,SLIIT, 2025-10-10) Piyumali, S. K. K; Manamgoda,D. S.; Udayanga, D
    Dyes are integral elements used to impart colours to textile materials. The wastewater effluent generated from textile industries during the processing and treatment of the dye contains inorganic and organic compounds that are hazardous, thereby posing a serious threat to ecosystems.This study focused on the assessment of the decolourization capability of textile dyes using eleven (11) ascomycetous fungal isolates, obtained from selected local dump site habitats in Sri Lanka.

    Synthesis of Amine Functionalized Silica- Cu4O3 Adsorbent from Rice Husk for Efficient Removal of Crystal Violet from Aqueous Solution
    (Faculty of Humanities and Sciences,SLIIT, 2021-09-25) Usgodaarachchi, L.; Thambiliyagodage, C; Angappan, S
    Silica based Nano adsorbent (SCN) synthesized using rice husk as the raw material via sol- gel pathway. Silica nanoparticles were successfully functionalized with 3-aminopropyl triethoxysilane (APTES) via in-situ functionalization method. Synthesized nanoparticles were characterized by XRD and FT-IR. The equilibrium adsorption capacity of 0.02g of SCN to adsorb 10 mg/L crystal violet (CV) was 20.09 mg/g. The influence of pH, adsorbent dosage, and initial CV concentration on adsorption of CV to SCN were studied. The equilibrium data for CV adsorption on SCN well fitted to Freundlich model, with a Freundlich adsorption capacity of 8.23 mg g-1. The adsorption of CV could be best described by the pseudosecond order model with 0.99 linier regression coefficient.
