Syntheses and crystal structures of two o-phthalate based transition metal complexes
We report the synthesis and the crystal structures of two complexes. The two metal complexes; (1) [Zn(bipy)2(HPht)](HPht)·H2O and (2) [Cu2(Pht)2(Bipy)2] ·4H2O (where Pht2― = dianion of o-phthalic acid, HPht― = anion of o-phthalic acid, Bipy = 2, 2′-bipyridine) have been synthesized and their crystal structures were determined by elemental analyses, IR and single crystal diffraction...

Simple and simultaneous spectrophotometric determination of Pd (II) in alloys using hydrazone compounds
A highly selective, reproducible and rapid spectrophotometric method for the determination of palladium (II) is developed based on the reaction of Pd (II) with 2,4-dihydroxyl acetophenone-p- hydroxylbenzoylhydrazone [RPPHBH] in the pH range 5 to 6 which forms a stable pale green complex. The complex shows absorbance maximum at 375 nm at pH of 5.5. Beer’s law is obeyed in the range 1.06 to 8.51 µg/ml of...

Effect of additive for efficient combustion of cracked furnace oil
Present communication deals with evaluation of various additives, formulations and chemicals that are either commercially available or synthesized in authors’ laboratory for cracked residual fuel oil. The objective of this study is to assess the suitability of these additives and chemical components with regard to sediment and deposit inhibiting characteristics and study the effect of the additives on actual fuel...

Emamectin benzoate residue analysis in ground and terrestrial field water in Lahore suburban area
High performance liquid chromatography with diode array detector was used to determine the ememactin residue in ground water in Lahore suburban area. The samples were extracted with chloroform through solvent extraction by using a separating funnel. The chemicals used were chloroform, methanol (HPLC grade) and acetonitrile (HPLC grade). Mobile phase used was acetonitrile (98%) and methanol (2%). 10 samples were analyzed...
