Modification of some organic compounds of pharmaceutical interest
In this article, the modification of the chemical structure of acetaminophen and ibuprofen is described. The esterification, acetaylation and hydrolysis products of acetaminophen and the nitration product of ibuprofen were prepared. The newly synthesized compounds were characterized by IR, 1H NMR and mass spectral analysis. The synthesized products will be tested and evaluated as antimicrobial...

Studies on the adsorption efficiency of activated carbon for pesticide vapour
Chlorpyrifos pesticides are endocrine disruptors, inhibitors of acetyl cholinesterase, used to control pests and prime contributors to indoor pollution in retail stores. Seven selected locally sourced adsorbents; Bone charcoal (BCA), corncobs, cotton seed, kokoli, sawdust, coconut shell (CSA) and Muruchi were evaluated. Only BCA and CSA shows peaks and were further examined at adsorptive temperatures of 283, 293, 303,...

Study of physical chemistry on biosorption of zinc by using Chlorella pyrenoidosa
Discharge of heavy metals from metal processing industries is known to have adverse effects on the environment. Biosorption of heavy metals by metabolically inactive biomass of microbial organisms is an innovative and alternative technology for removal of these pollutants from aqueous solution. Presence of heavy metals in the aquatic system is posing serious problems and zinc has been used in many industrials and...
