Muchlis, Amelia Talida (2018) Modifikasi Pasir Laut dengan Oksida Besi untuk Adsorben Parasetamol. Sarjana thesis, Universitas Brawijaya.
Abstract
Pasir merupakan batuan sedimen di permukaan bumi dengan diameter 2,00 – 0,02 mm. Dalam penelitian ini, dilakukan modifikasi pasir laut dengan oksida besi untuk mempelajari pengaruh jenis pasir dan oksida besi dalam komposit terhadap sifat fisikokimia dan adsorpsi parasetamol. Tahapan penelitian yang dilakukan adalah aktivasi pasir laut dengan HCl (temperatur kamar, 4 jam) kemudian pembuatan modifikasi pasir laut dengan oksida besi menggunakan metode kopresipitasi dengan FeCl3 pada perbedaan pH (9,5 dan 11,5) dan temperatur (temperatur ruang dan 500◦C). Karakterisasi adsorben dilakukan dengan menggunakan FTIR dan XRD. Uji Adsorpsi dilakukan dengan larutan parasetamol 50 mg/L. Digunakan parasetamol dengan konsentrasi 10-50 mg/L dalam penentuan kapasitas adsorpsi. Konsentrasi parasetamol ditentukan menggunakan spektrofotometer UV-Vis pada panjang gelombang 243 nm. Karakterisasi komposit menunjukan bahwa terdapat 2 jenis pasir pada sampel yang digunakan yaitu silika dan karbonat serta terdapat perbedaan serapan pada spektra dengan adanya modifikasi. Nilai adsorpsi terbaik terdapat pada modifikasi pasir dengan oksida besi pada pH 11,5 dengan struktur ferihidrit. berdasarkan model Freundlich, nilai k yang diperoleh sebesar 0,1127 mg/g.
English Abstract
Sand is sediment in the earth surface and have diameter between 2,00-0,02 mm. In this research, the sand was modified with iron oxide to study about the effect of sand’s type and iron oxide in the composite for parasetamol adsorption. The activation method used HCl at room temperature for 4 hours then modification process was coprecipitation method using FeCl3 in variation of pH (9,5 and 11,5) and temperature (room temperature and 500◦C). Characterization of adsorbent has done with FTIR and XRD. Adsorption test used paracetamol solution with concentration 50 mg/L. determination of adsorption capacity used paracetamol with concentration between 10- 50 mg/L. Paracetamol concentration determinded by UV-Visible Spectrophotometer and the wave lenght is 243 nm. The result of characterization shows that there were 2 type of sand in the sample, which are silica and carbonate, modification process made several difference in the spectra of the sea sand. The composite that give highest adsorption value is iron oxide-modified sea sand in pH 11,5 and have ferrihydrite structure. Based on Freundlich model, calculated k is 0,1127 mg/g.
