Effect of attendant anions on zinc adsorption and transformation in chernozem

• The effect of attendant anions on the Zn adsorption by soil was established.
• The mechanism of interaction of Zn cations with a solid soil phase was studied.
• Acetic acid anions had great influence on bond between metal and soil.
• The content of Zn mobile forms in soil depends on its penetration dose and form.

The effect of anions on the adsorption and mechanism of interaction of zinc cations with a solid soil phase was established. Acetic acid anions had the greatest influence on bond strength between metal and soil particle surfaces, while the effect of nitric acid anions was the lowest. The difference in amount of mobile forms of zinc extracted by the soil depends on the dose and form of the zinc. The influence of the attendant anions on the content of mobile metal forms in the soil decreases in the order: PO42 − ≈ Cl− > NO3− > SO42 − > СН3СОО− > О−.
