Preparation of Soil, Sewage, Sludge and Sediment Samples in the Wastewater Treatment Laboratory

Preparation of Soil, Sewage, Sludge and Sediment Samples in the Wastewater Treatment Laboratory

The preparation of a mixture of organic and inorganic samples holds some difficulties: whereas sand, clay and stones can usually be ground to homogeneous samples with suitable laboratory mills, the high energy input can cause samples with organic components such as fat or starch to cake. Waste water treatment laboratories...

Determination of Glyphosate in water and soil via Ion Chromatography

Determination of Glyphosate in water and soil via Ion Chromatography

Glyphosate, better known under the commercial name as ‘Roundup” is the most widely used herbicide in the world. Glyphosate (N-(Phosphonomethyl)glycine) is a broad spectrum, non-selective herbicide. It is the main component of Roundup (from Monsanto). It causes plant’s death by interfering with the production of certain amino acids. The glyphosate...
