This article describes a detailed comparison between the original BCR sequential extraction procedure, step 2 of which involves treatment with 0.1 mol l −1 hydroxylammonium chloride at pH 2, and the revised BCR procedure (step 2: 0.5 mol l −1 hydroxylammonium chloride at pH 1.5). An intermediate protocol was also evaluated in …

Copper extraction in step 2 was only marginally increased, relative to the original BCR protocol, when procedure B was applied. However, significant additional analyte was isolated in this step using procedure C. Procedure B recovered more lead in step 2 than procedure A, and procedure C more than procedure B, indicating that both the increased
Judging from the extraction of Fe and Mn from a secondary resource (The leaching residue from desulfurization and denitrification of exhaust gas treatment process with manganese ore as absorbent) including pyrolusite and goethite with a low Mn content (30.1%Fe and 4.0%Mn) (Deng et al., 2018), as well as manganese ores with a low Fe …
Hydrometallurgy is the most suitable extractive technique for the extraction and purification of manganese as compared to all other techniques including biometallurgy and pyrometallurgical processes.
The precision obtained in determining Ca, Mg, Zn and Mn by the HCl extraction method was generally comparable to that obtained by the triacid digestion method. These results suggest that the HCl extraction method can be used for routine and rapid analysis of plant tissues for Ca, Mg, Zn and Mn contents as well as for K content.
It is similar to the Bray P-1 test (a dilute acid and fluoride extraction for assessing phosphate; Bray and Kurtz, 1945), but includes a chelating agent (EDTA) to enhance the extraction of trace ...
Manganese (Mn) is an essential micronutrient for all organisms. In plants, Mn plays a critical role in photosynthesis and as a structural component of enzymes. In soils, Mn exists as different fractions of varying availability to plants. Mn fertilizers can be used to increase Mn availability to plants but are easily converted from a plant-available fraction …

Introduction. Manganese (Mn) is an essential element in virtually all living organisms where it can fulfill two different functions: acting as an enzyme cofactor or as a metal with catalytic activity in biological clusters (Andresen et al., 2018).In humans, Mn functions as a cofactor for a variety of enzymes, including arginase, glutamine …

A new sequential fractionation procedure was developed to minimise the problems of: (1) the dissolution of manganese (Mn) oxides by H{sub 2}O{sub 2} and NaOAc-HOAc at low pH, and (2) the release of specifically adsorbed cations by NaOAc-HOAc buffer used for carbonate extraction.
In this paper, a sample preparation method based on acid extraction of magnesium, manganese and zinc from plant tissue by means of high intensity probe ultrasonication is described. Acid extracts obtained upon sonication were directly nebulised into an air–acetylene flame for fast metal determination by atomic absorption spectrometry.
