NON-WASTE PROCEDURE FOR PRODUCING HYDROXYAPATITE FOR MEDICAL AND BIOLOGICAL USE
Abstract
A procedure has been proposed for non-waste laboratory-scale production of hydroxyapatite (HAP) which can be applied for medical use, i.e. for manufacturing bone implants. The procedure involves 2 steps: synthesis of HAP in a rotary pulsation apparatus by ion-exchange method providing sufficiently good yields of nano-scale particles followed by subsequent purification of the product. The key point of the developed procedure is further utilization of the wash waters from the purification step with their use as a mineral complex additive enriched with nitrogen, phosphorus, and calcium for feeding agricultural plants. It has been demonstrated that the resulting mineral complex contributes to the accelerated growth of plants in aggressive soils.
