| dc.description.abstract | Areca Nut Shells Fro,11 Agricultural Waste Can Be Used To Produce Cellulose, Which Is Then Converted Into Sodiu,N Carboxy,Nethyl Cellulose (Na-CMC). Cellulose Was Isolated Using A Con1binatio11 Of Two 111ethods, Naniel Ydiluteacid Treaunent With HNO1 And Alkalination With Naoh Solution, Yielding A-Cellulose Of 12.534 G(16.713% Of The Initial Weight). The Etheriftcatio11reaction With The Initial Stage Of Alkalisation, Na111el Y The Reaction Between Cellulose And Naoh In A ,Nixed Reaction 111ediu1n Of 100ml Isopropanol-Butanol (20:80) ( Vl V), With Variations Of Naoh 10%, 15%, 20%, And 25%, Was Used To Prepare Na-CMC, .Followed By The Carboxy111eth Ylation Stage With The Addition Of Sodiu111 Chloroacetate To Alkaline Cellulose. Na-CMC Was Obtained At 76.5%, 78.2%, 80.1%, And 79% Of The Starting Weight, Respectively. In The 20% Naoh Variation, The Highest Degree Of Substitution Was 0.61. According To The Results Of FTIR Spectrophoto,Netertesting, Na-CMC Has A Vibrational Peak In The Wave N11111ber Region Of 3250.2 Cni-1, Which Is The Absorption Band Of Rhe -OH Group, The C-H Stretching Group At Wave 11u111ber 2887.5 C,11·1 , A Typical Peak At Wave N111nber 1580.4 Cn(1, Which Shows The COO· Stretching Group, And 1408.9 Cni"1 C -H Bending Group On Carboxy,Nethyl. SEM Surfa Ce ,Norphology Analysis Revealed That The Surface Of The Fibres On Sodium Carboxy,Nethyl Cellulose Appeared Larger And Expanded Than The Surface Of A-Cellulose. | en_US |
