Abstract :The aim of this study with fish bones as a waste in fish processing is to investigate whether they can provide more efficient and multi-functional materials by chemical modification. As modification chemical, p-aminohippuric acid was selected and modified on the bone particle surface by esterification method. The results showed that surface modification was performed successfully. P-aminohippuric acid bonded on the surface of bone was calculated as 190.64 µmol/g. The point of zero charge insert ignore into journalissuearticles values(PZC); of bone apatite insert ignore into journalissuearticles values(H); and modified bone insert ignore into journalissuearticles values(HA5); was investigated and determined as 7.25 and 6.80, respectively. SEM-EDS spectrums showed that nitrogen element of p-aminohippuric acid on the surface of HA5 could be observed in EDS spectrum clearly. Additionally, nitrogen amount of Hand HA5 was detected as 8.037% and 8.565%, respectively.
