A galvanochemical method for the synthesis of iron lignosulfonate was developed. Metallic iron is gradually dissolved in a solution of lignosulfonates on contact with the material acting as a cathode of the short-circuited galvanic pair. The effect of the cathode material as well as duration and temperature of the process on the anodic dissolution of iron was studied under dynamic and static conditions. Anodic dissolution occurs in a solution of lignosulfonic acids approximately 5 times more rapidly than in a solution of lignosulfonates. Iron lignosulfonate synthesized using the galvanochemical method have high biological activity. Under vegetative conditions, they can be used as an anti-chlorosis preparation to prevent glandular deficiency in plants growing on carbonate soils. Unlike complexonates based on synthetic complexones, iron lignosulfonates are biodegradable and environmentally friendly.
