    Antibacterial Activity of Copper Oxide Nanoparticles
    (University of Management & Technology, 2017) Mehshaar Gul
    Antibiotic drugs are resistant against bacteria and there is need to search for new antibiotic drugs that are more resistant against these bacteria. Copper oxide nanoparticles were synthesized by using copper sulphate pentahydrate and sodium lauryl sulfate. To check the antibacterial activity of the copper oxide nanoparticles against different bacteria like Eschericia coli, Streptococcus mutans, Staphylococcus areus, Pseudomonas and Klebsiella pneumonia, petri dishes were prepared. Amoxicillin was used as standard antibiotic and distilled water was used as solvent. Amoxicillin is very famous antibiotics as compared to other beta-lactam antibiotics. It works against Gram‐negative bacteria more effectively as compare to Gram positive bacteria. Dilutions of copper oxide nanoparticles were prepared of 2%, 1% and 0.5% respectively. Nanoparticles were characterized by using XRD technique. Copper oxide nanoparticles showed the antibacterial activity against all of the bacteria by agar well diffusion method. Copper oxide nanoparticles showed the highest efficiency against Eschericia coli for 2% concentration and lowest efficiency against Pseudomonas and Klebsiella pneumonia for 0.5% concentration. Therefore, it can be concluded that copper oxide nanoparticles show efficiency against bacteria and can also be used as antibiotic in medicine field as well as in paints, coatings, and textile.

    Non-Extractive Spectroscopic Determination of Lead Metal in Blood Samples
    (University of Management & Technology, 2017) Batool Safia
    A validated, precised, accurate and simple spectrophotometric method has been worked out for the determination of Pb in human blood. Determination of Pb method is based on the reaction of lead with xylenol orange after the wet digestion of blood samples of HCV patients with HNO3 and H2O2. The absorption maxima occurred at 578 nm. This method is are alternative method for the amount of Pb in blood other than test methods applied in medical lab.

    Removal of Lead Ions from Water Using Bio Materials
    (University of Management & Technology, 2017) Afaq Saroor
    The water which people drink or use must be clean and clear from germs, chemicals and a lot of other water pollutants. Waste water is routinely being discharged to outer environment from homes, agriculture runoff, industry and manufacturing process this water contain petrochemicals, phosphate, nitrate, and heavy metal like Cr, lead, Fe, Mg and loads of other hazardous materials. This water needs to be purify before its use. Pakistanis a developing country so we have limited source we need to find inexpensive materials and way of water purification .So my focus is on water purification by using cheap biomaterial as adsorbent. From bio materials we chose Gaozaban (Borago Officinels) as and adsorbent. Waste Gaozaban and pure Gaozaban was used here in this study and we treated lead contaminated water through static (column) and dynamic (orbital shaker) method. After treating the titration method was used for the estimation of lead ion concentration removed from water.
