Commercial Laundry Water Characterisation

Surfactants are the major active ingredients of laundry detergents. Therefore, special attention should be focused on the treatment and disposal of laundry wastewater. The aim of this study was to characterise the wastewater from a commercial laundry over 30 days. Physicochemical analyses were performed, monitoring the content of nitrogen, phosphate, heavy metals, linear alkylbenzene sulphonate...

Spectrophotometric determination of the fungicides captan and folpet in their commercial formulations

Captan and folpet react with thiophenol in the presence of triethylamine in acetonitrile to form a bis (phenyl) trithiocarbonate which reacts with 2, 4dinitrophenyl hydrazine in the presence of hydrochloric acid to form corresponding hydrazone. The latter is transformed into an intense red quinoidal ion immediately on making solution alkaline. This observation have been made the basis of a simp...

Radiochemical purity and in vitro stability of commercial hippurans.

Good radiochemical purity of hippuran is important regarding the patient's radiation dose, primarily because of the high thyroid exposure from free iodide. The radiochemical purity and in vitro stability of 11 commercially available 131I, 125I, and 123I hippurans were analyzed by means of thin layer chromatography. Three different radioactive impurities were found in all hippuran samples: (a) f...
