    Analysis and treatment of fertilizer industry wastewater
    (UMT, Lhr, 2016) MUHAMMAD UMAIR
    This study is based on the analysis of the fertilizer industry wastes and their possible treatments to make it less hazardous.The single superphosphate (SSP) industry was chosen for this purpose. Samples of waste water collected from various drains of the industry. The analysis revealed that waste water contain high amounts of TDS( 2340 mg/l), Ca2+ (2160mg/l), SO42- (1766mg/l), PO43- (2638mg/l) and Pb2+ (16mg/l). The pollutants have been successfully reduced to lower values TDS(1000mg/l), Ca2+(1633 mg/l), SO42-(1254 mg/l), PO43-(2135 mg/l), Pb2+(8 mg/l) by using wheat bagass and TDS(1600mg/l), Ca2+(1186 mg/l), SO42-(1005 mg/l), PO43-(1884 mg/l), Pb2+(12 mg/l) by using rice husk and TDS(1400mg/l), Ca2+(1105 mg/l), SO42-(969 mg/l), PO43- (1633 mg/l), Pb2+(4 mg/l) by using animal charcoal.

    Synthesis, characterization and antibacterial activities of iron oxide nanoparticles
    (UMT, Lhr, 2015) MUHAMMAD UMAIR
    The importance of nanoparticles is increasing day by day due to their potential utility in the fields if biomedicines, photo catalysis and in nano composite materials. Iro oxide nanoparticles can be effectively used in biomedical field for drug delivery, MRI and magnetic hj^erthermia. In this study, synthesis, characterization, and antimicrobial properties of iron oxide nanoparticles was investigated. Iron oxide nanoparticles were synthesized by co-precipitation method with different routes and chemicals. Synthesized iron oxide nanoparticles were characterized by X-ray Diffraction, Scanning Electron Microscope, Energy Disperdive X-ray spectroscopy and UV-Vis Spectroscopy and antibacterial activity of synthesized nanoparticles was also measured by determining the inliibition zones against Gram (+) and Gram (-) bacteria. Gram (+) bacteria species was Bacillus subtilis and Gran (-) bacteria species was Escherichia colt. Antibacterial activity was measured by using agar diffusion method. Formation of nanoparticles was confirmed by XRD technique. XRD analysis showed that the average grain size of the synthesized iron oxide nanoparticles was 19.11nm, 18.16nm, and 14.37nm for method-1, method-2 and method-3 respectively. Surface morphology and particle size of iron oxide nanoparticles were confirmed by SEM analysis. EDX analysis was used to study the samples and this analysis has confirmed the presence of Fe and O in all samples prepared by co-precipitation method with different routes chemicals. The nanoparticles which were synthesized by three methods marked as U-3, U-4 and U-5 for method-1, method-2 and method-3 respectively. All the three samples have grain size in nanometer range as; 19.11nm for U-3, 18.16nm for U-4 and 14.37nm for U-5. Smallest grain size from all three samples was 14.37nm of sample U-5 was further subjected for band gap analysis. Theband gap for nanoparticles was measured as 1.46eV for sample U-5. Sample U-5 was also used for studying antibacterial activity against the Gram (+) and Gram (-) bacterial cultures and proved as an excellent antibacterial agent.

    Use of low cost biodegradable salts for cotton dyeing
    (UMT, Lhr, 2017) MUHAMMAD UMAIR
    Biodegradable salts was used for the dyeing of cotton with exhaust method that help to reduce the effluents and environment friendly. Sodium acetate trihydrate (C2H9NaO5) mixed with soda ash (NaHCO3) for maintaining the pH of dyeing solution for completion of reaction, clear and even dyeing occur. The analysis of color fastness to laundering (SDC multifiber strips were used for staining test), color fastness to crocking (dry crocking and wet crocking was investigated) and color fastness to light (blue wool reference scale was used for detection of color change) were studied. All dyed fabric specimens showed excellent results as compared to inorganic salts.
