Abstract

Hydroxyapatite is a biomaterial that has been recognized in terms of hard tissue engineering due to its similarity in composition to bioapatite. Moreover, abundant resources and diverse synthesis methods make hydroxyapatite easy to produce. The application in terms of 3D print-based network engineering is also being intensively explored due to hydroxyapatite scaffold fabrication process flexibility. In this review, various hydroxyapatite from natural sources, synthesis methods, hydroxyapatite-based 3D print filament fabrication techniques, as well as fillers used in the production of filaments are discussed.

Abstract

Boron is very dangerous for living things. The boron concentration allowed for drinking water is less than 1 mg/L. If not standard, boron causes nausea, lethargy, diarrhea, vomiting, dermatitis, and a risk of miscarriage in pregnant women. Thus, this research investigated the effect of variations in adsorbent dosage and pH on boron adsorption using the DMAPAA-co-DMAPAAQ hydrogel. The research began with the hydrogel synthesis process, which continued with the batch-mode sorption study. Based on research results, the higher the adsorbent dosage, the more boron is adsorbed. The highest removal percentage with an adsorbent amount of 0.5 g/L was 19.89% for pH 3, and for an adsorbent dosage of 2 g/L was 19.52% for pH 9. The highest percent removal was at pH 11. The DMAPAA-co-DMAPAAQ hydrogel adsorbent is shown to be environmentally friendly compared to commercial resins because the commercial resins are not biodegradable, making them difficult to recycle, causing more damage to the environment.
