摘要

This study explores the synthesis and application of hydroxyapatite nanoparticles (nHAPs) derived from eggshell waste as a sustainable alternative to chemically synthesized nHAPs, with a focus on agricultural applications. Using techniques such as SEM, EDX, FTIR, and XRD, the eggshell-derived nHAPs were found to exhibit a more uniform size distribution and higher calcium content compared to their chemically synthesized counterparts. Hydroxyapatite (HAP), a calcium phosphate compound, is increasingly recognized for its potential as a nanofertilizer in promoting sustainable agriculture. The synthesis of nHAPs from eggshells involves cleaning, drying, calcination, and chemical transformation, offering a cost-effective approach compared to chemical synthesis, while still allowing for controlled particle size and composition. Both types of nHAPs were functionalized with natural humic substances (HS) to enhance their efficacy as fertilizers. A comparative study using chilli plants as a model showed that those treated with eggshell-derived HAP exhibited accelerated growth and flowering, with 50% flowering achieved within 40 days. These findings highlight the potential of eggshell-based nHAPs as plant growth enhancers and sustainable agricultural inputs, addressing challenges in both agricultural productivity and waste management to support an eco-friendly future.
