Nitrate Removal from Aqueous Solutions Using Almond Charcoal Activated with Zinc Chloride
Background & Aims of the Study: Nitrate is one of the most important contaminants in aquatic environments that can leached to water resources from various sources such as sewage, fertilizers and decomposition of organic waste. Reduction of nitrate to nitrite in infant’s blood stream can cause “blue baby” disease in infants. The aim of this study was to evaluate the...
متن کاملRemoval of zinc from phosphate solutions by anion-exchange.
In plant nutritional studies. it is often necessary to prepare nutrient solutions that are free of a particular micronutrient. It is occasionally possible to obtain batches of nuitrient salts from commercial sources that are sufficiently loyv in a given micronutrient to be used in such1 deficiency studies. But as pointed out by Hewitt (2), it is muich more advisable in these instances, to use a...
متن کاملThe Structure of Zinc Chloride Complexes in Aqueous Solution
The structure of zinc chloride complexes with different ratios of chloride to zinc, formed in concentrated ZnCl2 aqueous solutions, were determined f rom large-angle X-ray scattering using concentrations of the chloride complexes estimated by complementary Raman spectroscopic measurements. The highest chloro complex, [ZnCl4]~, is tetrahedral with a Zn-Cl bond length of 2.294(4) Ä. The trichloro...
متن کاملStudies on removal of Zinc and Chromium from aqueous solutions using water Hyacinth
Phytoremediation is an eco-friendly method for removal of pollutants, which can be relied upon as a sustainable technology, if implemented under optimum conditions of plant growth. The effectiveness of water hyacinth, a topical weed, for the removal of Zinc (Zn) and Chromium (Cr) ions from aqueous solutions has been presented in this article. The potential of this plant in removing metals by ph...
متن کاملNonanomalous Electrodeposition of Zinc-Iron Alloys in an Acidic Zinc Chloride-1-ethyl-3-methylimidazolium Chloride Ionic Liquid
The electrodeposition of iron and Zn-Fe alloys on polycrystalline nickel was investigated in the 40.0-60.0 mol % zinc chloride1-ethyl-3-methylimidazolium chloride ionic liquid containing iron~II! at 90°C. Iron~II! was electrochemically reduced to iron metal before the reduction of zinc~II! to zinc metal, and anomalous codeposition of Zn-Fe did not occur in this ionic liquid. Underpotential depo...
