Iron Phosphate Slug Bait Warning

There is no doubt therefore that elemental iron can safely be described as toxic to humans in high enough amounts and that elemental iron is released by EDTA from iron phosphate Excess iron is not easily removed from the human body but the situation is worse for dogs which are the main problem with metaldehyde-based slug baits The iron LD50 for dogs is about the same as it is for people

Sodium Iron EDTA [NaFe(III)EDTA] as a Food Fortificant

Iron (Fe) deficiency is one of the major nutritional problems in the world among women of childbearing age children and infants (Bothwell et al 1979) The major causative factor in many developing countries is the poor bioavailability of Fe in the mainly cereal-based diets (Charlton and Bothwell 1983 Layrisse et al 1990) One way to increase the Fe intake in the population is via Fe

The determination of the stoichiometry of a metal complex

This method usually involves the use of metal complexing agents such as di-sodium EDTA iron (III) for various purposes (such as masking agents) 2-hydroxybenzoic acid combines with iron (III) forming a coloured complex This complex is then using a UV/visible spectroscopy The method employed in this experiment is the Job's method where different proportions of metal and reagent are mixed

EDTA

EDTA is a great chelating agent allowing multiple bindings in a coordination complex This gives it the ability to displace other undesirable ligands due to entropy and thermodynamics and is thus used in laboratories factories and in medicine The problem with its overuse is that it degrades into a toxin By having excess of this more toxin is created and left in the environment

Deciphering Chelating Agent Formulas

The oxidizing nature and pH of the formula—not the pH of the chelator—will determine the optimum efficacy of the chelating system since they can affect its stability 4 For each metal complex there is an optimum pH and an active pH range in which the metal complex is stable In addition the quantity of chelating agent required is dependent upon the concentration of the metal ion to be

Will Chelates Improve Plant Growth?

Iron – EDTA: releases the most iron to the soil but it is only good in acidic soil It is the common form found in most liquid fertilizers EDTA also has a high affinity for calcium and should not be used on soil with a high calcium level since it becomes ineffective at protecting iron EDTA works better with other metal ions at high pH Iron – DTPA: Effective up to a pH of 7 5 and not as

Iron Sources in Hydroponics : Which One is the Best

The fact is that although EDDHA binds iron much more strongly it decomposes easier within the hydroponic solution than EDTA or DTPA (this is due to the fact that EDDHA is composed of several different isomers some of which are not very stable) reason why this complex appears to be but is not the best solution for hydroponic nutrient solutions The best compromise between stability and
