ADSORPTIVE REMOVAL OF TEXTILE DYES (CIBACRON YELLOW CSG) FROM AQUEOUS SOLUTION BY COCONUT COIR CARBON

This report consists of four important chapters that cover the introduction, problems
statement, objectives of the projects, review of related literature, project methodology and the
conclusions. The introduction part briefly discusses the background of the textile dyes. For the
second part, the focus is more on the problem statement that covers problem identification and
the significant of the projects. Part three is where the objectives of the project are stated and it
describes more on the relevance and the feasibility of the project within the scope and time frame
given. The review of related literature on textile dyes and coconut coir is enclosed in part four
while the project methodology is covered in part five of the report. The project conclusion is also
stated in the report together with the references used while doing research works on this project.
The objective of this project is to investigate the effectiveness of coconut coir carbon in
adsorptive removal of textile dyes from aqueous solution. It is found to be maximum removal of
82.55 and 73.3 % in 0.1 g coconut coir activated carbon for 5 hours contact time in 2 mg/L and 5
mg/L of CYC5G concentration respectively. From the adsorption study, maximum adsorption
capacity of 4.028 and 9.278 mg/g of coconut coir activated carbon were observed at an adsorbent
dose of 0.4 giL in 2 mg/L and 5 mg/L of CYC5G concentration respectively. From the column
studies, it has shown that the adsorption is greater at the slow rate of flow and in thicker bed
depth.
