Abstract

This study investigates the syntesys of hydroxyapatite (HAp) from chicken bone waste, which is abundantly available due to high poultry production, using a high-temperature method. The objective of this study was to determine the effect of variations in sintering temperature (300, 400, 500, and 600°C) and sintering time (3, 4, 5, 6, and 7 hours) on the yield and Ca/P ratio of the HAp produced. The prepared chicken bone powder was first calcined at 900°C for 3 hours before sintering. The results showed that the optimal conditions were 600°C for 7 hours, characterized by a change in the sample's colour to white and a yield of 69%. XRF analysis confirmed the formation of HAp with a Ca/P ratio of 1.69. It was concluded that a sintering temperature of 600°C for 7 hours is optimal for producing pure HAp from chicken bone waste.

Abstract

The brine solution remaining after salt crystallization contains high levels of valuable minerals, particularly magnesium, which can be extracted and processed into magnesium chloride (MgCl₂), a compound widely used in various industrial applications. This study examines the effect of hydrochloric acid (HCl) concentration and calcination temperature on the yield of MgCl₂ synthesized from brine-derived magnesium hydroxide. Magnesium hydroxide was precipitated using sodium hydroxide and subsequently reacted with HCl solutions of varying concentrations (1N–5N) before being calcined at temperatures ranging from 350°C to 550°C. The results show that both HCl concentration and calcination temperature significantly influence the product yield. The highest yield, 80.07%, was obtained at an HCl concentration of 4N and a calcination temperature of 550°C. While increasing acid concentration and temperature generally improved yield, concentrations above 4N did not provide further benefits and instead tended to decrease efficiency. These findings highlight key processing parameters for optimizing MgCl₂ production from brine, contributing to more efficient resource utilization and environmentally sustainable mineral processing practices.
