Abstract

Coconut (Cocos nucifera L.) is the most important and extensively grown palm tree in the country with a total cultivation area of 3.3 million hectare and annual production of 15,667,600 tons. However, utilization of the by-products was given less attention. With the development of nanotechnology having high specific surface area and highly porous wit highly pore interconnectivity composites can be used for further applications such as nano-filtration system. The study used nano-composite from novel clay reinforced to cellulose acetate derived from coconut husk to develop and fabricate a nano-filtration system. Produced nano-fibers were blends of PLA, cellulose acetate from coconut husk, chitosan and ALA-MMT. FTIR analyses revealed carbonyl group, CH2 bending, asymmetric ester group that is a band characteristic of PLA and CA, asymmetric stretching of pyranose and CH2 bending bands revealing the polymer blend of the treatments used. SEM analyses showed no significant difference among treatments. Hence, increasing voltage from 25kv to 30kv showed no effect the diameter size of the fibers. Also, the results confirmed non-toxicity and antibacterial property of the nano-fibers in terms of growth inhibition as per higher content of cellulose acetate and chitosan. Prior to coconut water analysis, results showed significant difference at 0.05 probability level among all the water samples depicting that stage of filtration affects the quality of water decreasing the colony forming of microorganisms hence prolonging the shelf life and quality of water comparable to water filtration system passing through sieve mesh and pasteurization.
