Alwy, Muhammad (2019) Adsorpsi Zn(II) Mengunakan Adsorben Kitosan Mikro Partikel. Sarjana thesis, Universitas Brawijaya.
Abstract
Pada penelitian ini telah dilakukan modifikasi adsorben kitosan menjadi kitosan mikro partikel untuk meningkatkan kemampuan adsorpsinya terhadap ion Zn(II). Kemampuan adsorpsi kitosan mikro partikel terhadap ion Zn(II) dilakukan dengan menentukan kondisi optimum adsorpsi meliputi : pH dan lama kontak. Penentuan pH optimum dilakukan dengan variasi pH 3, 4, 5, dan 6, sedangkan penentuan lama kontak optimum dilakukan dengan variasi lama kontak 30, 60, 90, dan 120 menit. Selanjutnya kondisi optimum adsorpsi digunakan untuk menentukan kapasitas adsorpsi kitosan mikro partikel dengan memvariasi ion Zn(II) 100, 125, 150, 175 mg/L. Berdasarkan karakterisasi mengunakan spektra FTIR secara umum tidak terjadi perubahan gugus fungsi dari kitosan menjadi kitosan mikro partikel, tetapi modifikasi ini hanya berdampak pada morfologi dan ukuran partikel sesuai hasil analisa SEM. Kondisi optimum adsorpsi ion Zn(II) mengunakan kitosan mikro partikel terjadi pada pH 5 dengan prosen adsorpsi sebesar 58,21% dan lama kontak optimum terjadi pada 90 menit dengan prosen adsorpsi sebesar 86,90%. Kapasitas adsorpsi kitosan mikro partikel pada ion Zn(II) sebesar 22,39 mg/L.
English Abstract
In this study, modifications of chitosan adsorbent have been made to micro particles chitosan to increase the ability of adsorption to Zn(II) ions. The ability of chitosan micro particles adsorption on Zn(II) ions was carried out by determining optimum adsorption conditions including: pH and contact time. Determination of optimum pH was carried out with variations in pH 3, 4, 5, and 6, while the optimum determination of contact length was carried out with contact length variations of 30, 60, 90, and 120 minutes. Furthermore, optimum adsorption conditions were used to determine the adsorption capacity of micro chitosan particles by varying Zn(II) ions 100, 125, 150, 175 mg / L. Based on the characterization using FTIR spectra in general there was no change in functional groups from chitosan to micro chitosan particles, but this modification was only affected by morphology and particle size according to the results of SEM analysis. The optimum conditions for the adsorption of Zn(II) ions using micro chitosan particles occurred at pH 5 with an adsorption process of 58.21% and the optimum contact time occurred at 90 minutes with an adsorption process of 86.90%. The capacity of micro-chitosan adsorption on Zn(II) ions was 22.39 mg / L.
