Fruit peels are low cost lignocelluloses matter which generated from many food processing industries and household as a organic waste. They have some potential for recyclization. In this paper two fruit peel lemon and watermelon which is easily available in large volume was taken to analysis. There physical, chemical and surface characterization was done. The fruit peel was analyzed by SEM, EDX and FTIR spectra to identify textural structure, chemical analysis of various functional group and element. The pH value and pHpzc was found in the range of 5-6. The water absorption capacity and iodine value was examined higher for lemon peel 11.5 (ml/g) and 122.78mg/g respectively. The micropores were present in higher number in lemon peel and watermelon peel exhibited angular fibrous structure. An FTIR spectrum was strongly associated with the presence of various functional groups like carboxylic acid, ester, amino acid and alcohols. This study provide better results to interpret resources of this two fruit peel and suggest that biomaterial is identified as a novel adsorbent with low cost value.
