    Abstract: As a low cost adsorbent source, a mixture of activated animal bones has been investigated on their efficiency in chromium ion removal from aqueous solution. Adsorption parameters such as contact time, biosorbent size, pH, biosorbent dosage, temperature and concentrations were investigated. Maximum adsorption of hexavalent chromium occurred at 35min...

    Abstract: An investigation has been made to find out the disease altering therapies against a somber ailment called ‘early aging’ which is due to the formation of free radicals during the natural course of metabolism, also act randomly and indiscriminately to damage the cell components. On the contrary, the natural antioxidants in dietetic practice can dimin... Show More
