Abstract

Penelitian tentang penurunan kadar linear alkylbenzene sulfonate (LAS) dalam limbah laundry menggunakan abu sekam padi telah dilakukan. Tujuan dari penelitian ini untuk mengetahui kinerja adsorpsi dari abu sekam padi dengan optimasi pH, berat, waktu kontak, konsentrasi dan kapasitas pada proses adsorpsi. Rendemen abu sekam padi yang diperoleh sebesar 28,58 %. Kondisi optimum penjerapan pada 2 mg/L linear alkylbenzene sulfonate (LAS) sebanyak 150 mL menggunakan 0,4 g abu sekam padi yaitu pada pH 5 dalam waktu 30 menit dengan kapasitas adsorpsi maksimum 3,894 mg/g. Hasil penurunan kadar LAS pada limbah laundry dari 1,8661 mg/L menjadi 0,465 mg/L ppm yaitu sebesar 75,013 %.

Abstract

Research on the synthesis of sulfonated mesoporous Silica from bamboo leaves ash (Dendrocalamus asper) as Heterogeneous Acid Catalyst has been conducted. Bamboo Leaf Ashfish serves as a source of silica for the manufacture of Mesoporous Silica. The research phase consisted of synthesis of MSU-H with surfactant template method, mesoporous silica modification with 3-mercaptopropyl-trimethoxysilane (MPTMS) using post grafting method. The mesoporous silica has a pore volume of 1.03 cm3/g, a surface area of 150 m2/g and a pore diameter of 27.5 nm. The FT-IR spectrum of mesoporous silica before sulfonation shows the presence of Si-O-Si, and Si-OH functional groups while that of Mesoporous silica after sulfonation shows the presence of Si-O-Si, Si-O, Si-OH and –SO3H functional groups.
