Preparation and characterization of rhacfapfa sorbent for the removal of acid violet dye_Ahmad Shahril Mohamed Noor_A9_2011_NI
Air sisa yang mengandungi pencelup daripada pelbagai industri seperti industri tekstil selalu menyebabkan masalah alam sekitar dan ia berkait rapat dengan isu estetika. Dengan menggunakan sisa industri di Malaysia yang mudah didapati dan sumber yang banyak, kajian ini telah dilakukan untuk mengkaji kemungkinan penggunaan abu sekam padi, abu arang dan abu kelapa sawit dalam menyingkirkan pencelup daripada larutan akues. Kajian ini memfokuskan terhadap penyingkiran pencelup ungu asid daripada larutan akues menggunakan kaedah penjerapan dengan penggunaan bahan serap yang dihasilkan daripada kombinasi abu sekam padi, abu arang dan abu kelapa sawit. Kajian kelompok telah dijalankan untuk memeriksa kesan pelbagai parameter seperti kepekatan awal pencelup, masa goncangan, kadar goncangan dan pH. Ia juga akan menentukan keberkesanan bahan serap dalam menyingkirkan warna dan sebagai rujukan untuk kajian masa hadapan. Daripada kajian kelompok yang telah dilaksanakan, didapati masa goncangan optimum adalah 80 minit sementara pH optimum adalah 2. Penjerapan pencelup telah diterangkan oleh garis sesuhu Langmuir, Freundlich dan Temkin. Garis sesuhu Freundlich menunjukkan analisa yang lebih sesuai berbanding dua garis sesuhu yang lain. Analisa fizikal dan kimia juga telah dilakukan untuk megkaji sifat fizikal dan kimia. Mikroskop pengimbas elektron digunakan untuk memeriksa struktur permukaan bahan serap dan pemancaran sinar-X digunakan untuk mengenalpasti struktur kristal yang hadir dalam bahan serap. Analisa permukaan telah memeriksa luas permukaan dan isipadu di dalam bahan serap. ___________________________________________________________________________________ Wastewater containing dye from various industries such as textile industries often caused environment problems and which were closely related with aesthetic issues. By using locally available and abundant resources of industrial waste in Malaysia, this research was conducted to explore the possibility of using rice husk ash, coal fly ash and palm oil fuel ash for the removal of dye from aqueous solution. This research focused on the removal of acid violet dye from aqueous solution using adsorption method where combination of rice husk ash, coal fly ash and palm oil fuel ash were used as sorbent. Batch studies were carried out to investigate the effect of various parameters such as initial dye concentration, shaking time, shaking rate and pH. It also determined the effectiveness of sorbent for removing color which would be referred for future research. From the studies those have done, the optimum shaking time was 80 minutes while the optimum pH is 2. Adsorption of dye was described by Langmuir, Freundlich and Temkin isotherm. Freundlich isotherm showed a better fit compared to the other two isotherms. Chemical and physical analyses were done to study its physical and chemical properties. Scanning electron microscope was used to examine the sorbent surface morphologies and X-Ray diffraction was used to identify crystal structure presents in the sorbent. Surface analysis was investigated the specific surface area and the volume in the sorbent.
