Abstract:

Cellulose from durian peel was isolated then esterified using citric acid with cellulose ratio used 1: 1, 1: 2, and 1: 3 (w / w). The formation of cellulose citrate from the esterification of cellulose with citric acid is evidenced by FT-IR spectroscopy analysis which gives the vibration spectrum of C = O carboxylate groups at the 1735 cm-1 wave region and is supported by the -OH group vibration in the 3448 cm-1 wave region. The results of morphological analysis using SEM also showed large morphological changes and cavities. Testing of adsorption power on Pb2 + metal ions (at concentrations of 100, 200, 300, 400 and 500 ppm) analyzed using atomic absorption spectrophotometers showed maximum absorption of cellulose present at a concentration of 100 ppm absorbing at 43.0804%, and maximum absorption of cellulose citrate 1 : 3 is present at a concentration of 100 ppm absorbing at 92.5000%.
