Obtainment activated carbon by processing plum stones and using them in industrial wastewater purification

Abstract

The article describes the technological features of the obtaining process of an import-substituting adsorbent with high adsorption properties from local raw materials, massively grown in our republic, waste plum stone, as well as the indicators of wastewater treatment from a pesticide and mineral fertilizer workshop. These adsorbents are intended for wastewater treatment from industrial enterprises. The research methods were carried out based on samples presented in the literature and standard GOST indicators. According to the results, carbon activated with steam at a temperature of 800 °C showed its effectiveness with higher adsorption properties compared to samples activated with acid and alkali. Therefore, this sample was used to purify wastewater from a pesticide and mineral fertilizer workshop. In conclusion, we can say that after thermal pyrolysis and steam treatment, the release of the elements O2 and Si from the plum pit leads to an increase in the amount of C and higher adsorption properties of the resulting activated carbon.
