Penentuan ukuran partikel kalsium laktat kerabang telur ayam melalui metode presipitasi dengan pendekatan persamaan Scherrer

Abstract

The recent development of nanotechnology has facilitated the enhancement of calcium particle absorption by manipulating particle size to the nanoscale. The objective of this work was to quantify the dimensions of calcium lactate extracted from chicken eggshell calcium oxide and commercial calcium oxide using the precipitation technique used with the Scherrer equation approach. The synthetic process was conducted by reacting 20 ml of a calcium oxide solution with a concentration of 1 mol/L and 30 ml of a lactic acid solution with a concentration of 6 mol/L. The two solutions have a volume ratio of 1:1.5 (v/v). The reaction was conducted for 30 minutes at a temperature of 50°C, with agitation using a magnetic stirrer spinning at 500 rpm. Following that, 20 ml of a 50% ethanol (v/v) solution was added, and the mixture was dried in an oven set at 105°C for 72 hours and then pulverized to produce calcium lactate powder. The particle size of calcium lactate was determined by the Scherrer equation method. The calculated data were experimentally evaluated using descriptive quantitative methods. According to the research, the production of calcium lactate from commercial calcium oxide and chicken eggshells resulted in particles with sizes of 85.69 and 85.33 nm, respectively. The research result showed that the precipitation technique for calcium lactate production could produce particles of nanoscale sizes.
