The pre-oxidation of an extremely polluted pharmaceutical wastewater (chemical oxygen demand (COD) value of 362,000mg/l) using the Fenton's reagent has been systematically studied using an experimental design technique. The parameters influencing the COD removal of the wastewater, namely temperature, ferrous ion and hydrogen peroxide concentrations have been optimized to achieve a COD global re...

Wastewater management in two companies representing the pharmaceutical industry was investigated and implemented. The results showed that the integration of the pollution prevention approach followed by an equalization tank reduced the organic load up to 70%, while further chemical treatment using either alum or ferric chloride aided with lime produced a quality of effluent suitable for restric...

The reaction of the drug atenolol with hypochlorite under conditions that simulate wastewater disinfection was investigated. The pharmaceutical reacted in 1h yielding three products that were separated by chromatographic techniques and characterized by spectroscopic features. Two unusual products 2-(4-(3-(chloro(2-chloropropan-2-yl)amino)-2-hydroxypropoxy)phenyl) acetamide and 2-(4-(3-formamido...

Natural products involved in plant-plant and plant-microorganism ecological interaction (Allelochemicals) are an important potential source for alternative agrochemicals and pharmaceuticals, in order to solve the many problems derived from inadequate culture practices and abuse of synthetic herbicides. Isolation, structural determination, bioassay techniques and applicability for these compound...

This experimental study aimed to compare the adsorption of oleic acid (fatty acid) by two adsorbent; activated carbon and carbon nanotube by use of Uv-Vis spectrophotometer Jenway 6505 model. In this study, five different concentrations of oleic acid in the range of 282.47ppm to 847.41ppm were used. In all conducted experiments, the values of adsorbents, exposure time, temperature, and pH were ...

The present research involves effectual parameters on Cefixime trihydrate removal from aqueous solutions. Antibiotics are the main contributions in pharmaceutical waste; their presence causes major concern. The extensive utilization of antibiotics in aquaculture and prescriptions has led to the cultivation of various antibiotic-resistant bacteria and genes in wastewater. The UV-LED/S2O82- pr...

Over the past few years, residual pharmaceuticals (antibiotics, anticonvulsants, antipyretics drugs, hormones) have begun to be considered as emerging environmental pollutants due to their continuous input and persistence to aquatic ecosystem even at low concentrations. Therefore, the development of efficient, cost-effective, and stable methods and materials for the wastewaters treatment have g...

Background: A typical sewage treatment plant is designed for organic and nutrient removal from municipal sewage water and not targeted to eliminate micropollutants such as pesticides, pharmaceuticals, and nano-sized metals which become a big concern for sustainable human and ecological system and are mainly discharged from sewage treatment plant. Therefore, despite contaminant removal by wastew...
