In this paper the results of investigation of the polyphosphate glasses dissolution in acid solution at temperatures of 20, 30 and 37 °C were presented. The dissolution process in citric acid is complex and can be explained by hydration reaction and hydrolysis, leading to the disruption of phosphate chains which form the structure of glass. Mechanism of chemical reactivity of polyphosphate glasses, acting as slow release fertilizers in soil solutions was presented. The results of the dissolution experiments indicated that this glass can be used as an eco- fertilizer in soil remediation.
