Nafion-modified mercury thin film electrodes have been investigated for the analysis of trace metals in environmental samples of waters and effluent by batch injection analysis with square wave anodic stripping voltammetry. The method. involving injection over the detector electrode of untreated samples of volume of the order of 50 microlitres has fast response. blocking and fouling o... https://parisnaturalfoodes.shop/product-category/flax-oil/
