Abstract
This study deals with the removal of Pharmaceutical pollutants such as Diclofenac, which caused hazardous pollutant for human health, from aqueous solution. The aim of this study is an investigation to remove the diclofenac from synthesis wastewater by using of pillared clay that made from Iraqi clay (ALAnbar clay) as adsorbent by using both batch and packed bed reactor to study kinetic model. The experimental work in batch reactor using different parameter (diclofenac, pillared clay and pH) in four beakers for 3 hours in jar test instrument , from the result show pH is the important factor effect on the adsorption process and also show diclofenac removal decreased with increasing pH values, but in constant all parameter effect of the initial concentration of diclofenac in the adsorption process show removal of diclofenac increasing with increasing the amount of adsorbent dosage up to 1000 mg. additional, the result of experimental work in packed bed reactor with different variables such as (initial concentration, flow rate and bed depth) for 6 hours, show the best condition of bed depth is 2 cm, initial concentration 625 mg /l and flow rate 25 h/l.
Highlights
Pharmaceuticals in the last years have become potential bioactive chemicals in the environment
Most studies have been carried out on the removal of pharmaceutical preparations that focused on a small group of processes or water treatment processes, they have used humic substances extracted from peat instead of water, which have different properties, including a fewer tent of humic acids than fulvic acids, molecules of lower molecular weight and less intensive structures, which may impede the removal of pharmaceutical preparations [9]
The operation condition has been used in packed bed reactor for all adsorbent were bed height of produced adsorbents (1, 1.5, 2 cm), initial concentration (100, 400, 625 mg/l) and flow rate 25 l/hr
Summary
Pharmaceuticals in the last years have become potential bioactive chemicals in the environment. They are causes a rising in pollutants in water bodies and the environment because they remain unfettered or undergoing a regularization process, while the information and legal frameworks are not complex yet. Most studies have been carried out on the removal of pharmaceutical preparations that focused on a small group of processes or water treatment processes, they have used humic substances extracted from peat instead of water, which have different properties, including a fewer tent of humic acids than fulvic acids, molecules of lower molecular weight and less intensive structures, which may impede the removal of pharmaceutical preparations [9]
