Background: Coagulation is a treatment procedure for metalworking fluids (MWFs). This study aimed to optimize coagulation using four coagulants and compare the results. Methods: In this research, the outputs of a coagulation procedure in chemical oxygen demand (COD) removal, turbidity, and the release of oil were investigated using four coagulants, ferric chloride (FeCl3), ferric sulfate (Fe2(...

In this study arsenate [As(V)] removal from drinking water by coagulation process was investigated. Ferric chloride (FeCl3.6H2O) and ferrous sulfate (FeSO4.7H2O) were used as coagulant. The effects of major operating variables such as coagulant dose (1–30 mg/L) and pH (5.5–9.5) were investigated. Ferric chloride and ferrous sulfate were found as effective and reliable coagulant due to required ...

heavily polluted wastewater from sanitary landfill presents the leachate characteristics that need special treatment and disposal. concentration of chemical oxygen demand (cod), ammonia nitrogen (nh3-n), heavy metal and other pollutant content are often larger than standard requirement after applying biological/physico-chemical treatment.thus, the combination of coagulationflocculation and chem...

The reagent described is 5.5 M in perchioric acid and 3.3 M in urea. It contains ferric ions, mercuric thiocyanate, mercuric ions (from mercuric perchiorate), and mercuric chloride. Serum dissolves directly in this reagent to yield a clear, reddish solution. When chloride ions are added, they combine first with the free mercuric ions, and then with some of the mercuric ions from the mercuric th...

Monsel’s solution (ferric subsulphate) is an iron salt first described in the literature in 1856 by Leon Monsel (1). Since then it has been widely used by dermatologists as a haemostatic agent in minor surgical procedures, such as tangential excision and punch biopsy (2). Ferric chloride is also a source of ferric ions, which is used in dermatological procedures and is considered more convenien...

The effect of iron on the attachment of gonococci to human spermatozoa was investigated using the three iron salts, ferric chloride, ferric nitrate, and ammonium ferric citrate (AFC). Ferric chloride and ferric nitrate were found to be unsuitable for such studies because they were insoluble at physiological pH values, produced a marked decrease in the pH of unbuffered medium (Ringer's solution)...

The solvent free route for the synthesis of diaryl sulfoxides from arenes and thionyl chloride in the presence of Lewis acids such as aluminum chloride and ferric chloride on silica gel are described.
