So far the application of chitosan as an adsorbent still uses microscale chitosan adsorbent. The microscale chitosan has not adsorbed waste maximally either to the weight of the adsorbent usage or the target adsorption capacity. Nanoscale adsorbent size has not been widely used, especially as an adsorbent of dyes waste. Therefore, through micro-size reconstruction into nano chitosan will provide maximum opportunities in its utilization. This study reconstructs the size of chitosan into nanochitosan and binds crosslinking with phosphate. Synthesis using ionic gelation method. The crosslinked results were characterized using FTIR, PSA and SEM-EDX instruments, followed by parameter optimization including pH optimization, interaction time, adsorption capacity and application. The amount of absorbed dye concentration was analyzed using UV-Vis spectrophotometer. The measurement results showed that the physical reconstruction of chitosan was successfully carried out with a wavelength range of 246nm-260nm as an indication of nanochitosan adsorbent at pH 7-9 using 5% nanochitosan. It was concluded that the nanochitosan from the synthesis could be reused for 2 times, with desorption percentage of 86%.
