Sustainable urban drainage systems (SuDS) such as swales are designed to collect, store and infiltrate a large amount of surface runoff water during heavy rainfall. Stormwater is known to transport pollutants, such as particle-bound Potential Toxic Elements (PTE), which are known to often accumulate …

In this research several methods were developed and validated using the Supermini 200 wavelength dispersive X-ray fluorescence spectrometer. A multielement was calibrated containing 26 elements and corrected for interference according to the de Jongh algorithm. The limits of detection and quantification …

Sustainable urban drainage systems (SuDS) such as swales are designed to collect, store and infiltrate a large amount of surface runoff water during heavy rainfall. Stormwater is known to transport pollutants, such as particle-bound heavy metals, which are known to often accumulate in the topsoil. In …

Sustainable Urban Drainages Systems (SuDS) are designed to collect, store and infiltrate large amount of surface runoff water during heavy rainfall. Surface runoff water is known to transport pollutants such as particle bound heavy metals. Therefore, a build-up of pollutants in the top-soil, of the commonly …

This report discusses the easy and cheap preparation of SnCl2 exchanged Brønsted acidic Amberlyst-15 ion exchange resin prepared by ion exchange of an aqueous SnCl2 solution at room temperature. The prepared materials were tested in the conversion of sugars, being glucose, fructose and saccharose to …

Het onderwerp van het onderzoek is de toepassing van een XRF-onderzoek op bronzen kookpotten. De bronzen kookpotten die gemeten zijn komen uit grote collecties uit Nederlandse musea en depots. Het doel van het onderzoek was het achterhalen van de samenstelling van het brons van kookpotten. Er zijn nog …

Vanaf 1 januari 2020 is het voor alle schepen verboden om brandstof te gebruiken die meer dan 0.50% m/m (massa/massa) zwavel bevatten tenzij, het schip is uitgerust met een scrubberinstallatie of een ander goedgekeurde methode door de IMO om SOx uit de uitlaatgassen te filteren. Dit betekent dat ongeveer …

Stormwater runoff has severe negative and direct impact on the quality of surface waters and groundwater. The impact can cause chemical and heavy-metal pollution. Applying well established methods to map pollutants in urban areas and specifically in Nature-Based Solutions (NBS), such as Sustainable Urban …

Omdat de oudste wadi in Nederland nu twintig jaar is, is oriënterend onderzoek gedaan naar de bodemkwaliteit van dertig wadi’s. Het onderzoek is uitgevoerd met de meettechniek XRF (X-ray Fluoresence). De XRF meet diverse elementen (waaronder zware metalen) door röntgenstralen uit te zenden.
