Effect Of Oily Wastewater Head Spills Of The Refineries On The Diffusion Rate And Contamination Of Soils – A Case Study Of Kawergosek (Erbil City) Refinery, Frzand K. Ahmed Medhat Jun 2020

Effect Of Oily Wastewater Head Spills Of The Refineries On The Diffusion Rate And Contamination Of Soils – A Case Study Of Kawergosek (Erbil City) Refinery, Frzand K. Ahmed Medhat

Polytechnic Journal

Field study works have been carried out to investigate the diffusion rate of oily wastewater on clayey soils and measuring the degree of contamination with chemical components for both horizontal and vertical directions. Three pits have been prepared for this work with 30 cm in diameter and 50 cm in depth, which are lying on a straight line and 100 cm clear distance between them. Three, 30 cm diameter plastic pipes were fixed inside the pits having the length of 50 cm, 150 cm, and 200 cm, respectively, to study the effect of the height of the spilled oily wastewater …

Spectrophotometric Determination Of Carbamazepine In Pharmaceutical Formulations Based On Its Reaction With A Brominating Agent, Warda Rizgar, Diyar S. Ali Dec 2019

Spectrophotometric Determination Of Carbamazepine In Pharmaceutical Formulations Based On Its Reaction With A Brominating Agent, Warda Rizgar, Diyar S. Ali

Polytechnic Journal

Two accurate spectrophotometric methods described for the estimation of carbamazepine (CBZ) in both pharmaceutical and pure form. These methodologies are attached to the bromination of CBZ by bromine formed in instantly from the bromate-bromide reaction. The general procedure includes the additional of a known amount of bromate-bromide reagent in an acidic mediocre to CBZ. After the reaction is integrated, the unreacted bromine was reacted with a steady amount of methylene blue, and the absorbance was measured at 665 nm (method A) or, cresol red could be used for the reaction and the absorbance moderated at 517 nm (method B). Beer’s …
