Anti Chlorine

As we know that anti chlorine agent will bound harmful metal containing substances and render them safely. The question is will it also bound the substances in liquid fertilizer such as iron(Fe), Zinc(Zn) etc? Thank you.

as far as I know,no.also those elements are found chelated in liquid fertilizers so nothing can be further changed

A GREAT question, Steven! I've wondered that myself!

While I agree with you that chelated compounds are nearing a thermodynamic sink, to suggest that they are devoid of reactivity would preclude their uptake and utilization by plants. The chelated nutrient metals can still undergo reactions with thiosulfate, but the nature of the metals is what will untimatly determine their divergent paths from toxic heavy metals.

The 'anti-chlorine' compounds discussed in this thread is the sodium salt of the thiosulfate anion which is the active compound which reduces (give electrons) to hypochlorite (bleach) to render it as a harmless chloride anion.

Thiosulfate will ultimatly reduce iron (as an example of a nutrient) which is in the (3+) oxidation state to the (2+) oxidation state. However in our oxidizing atmosphere (~21% O2) iron is quickly oxidized to iron (3+) again. So it will have no effect.

However, the inherent reactivity of toxic heavy metals is vastly different. For example mercury (2+) will react with thiosulfate to form insoluable mercury sulfide. Other examples of heavy metals form very stable and soluable complexes which are then not uptaken my organisms.

These differences in reactivity, in part, determine why heavy metals are so toxic - the formation of strong, stable complexes with our own sulfur containing proteins.
