Manganese removal from synthetic Wastewater using pyrolyzed chicken Feather fiber (pcff)

Manganese removal from synthetic Wastewater using pyrolyzed chicken Feather fiber (pcff) / Nur Fajrina Ahamad Lazin
Kehadiran logam berat dalam air sisa menimbulkan pelbagai kesan negatif kepada kesihatan manusia dan alam sekitar. Pelbagai usaha giat dijalankan dalam menghasilkan bahan penjerap kos rendah untuk penyingkiran logam berat seperti kalsium, zink, magnesium, dan mangan dari air sisa. Karbon aktif sedia ada adalah tinggi harganya namun pelbagai usaha inovasi dan penyelidikan kini giat dijalankan ke arah penghasilan karbon aktif dari produk sisa semula jadi seperti penggunaan gentian bulu ayam. Langkah alternatif ini adalah lebih mudah, murah dan bersifat mesra alam untuk rawatan air sisa. Dalam kajian ini, penyingkiran logam berat dari air sisa sintetik kategori mangan dilaksana menggunakan gentian bulu ayam yang dipirolisis (PCFF). Gentian bulu ayam yang dipirolisis (PCFF) bertindak sebagai karbon aktif dalam rawatan air sisa dan dipirolisis menerusi suhu 195°C selama 5 jam di pirolisis pertama dan suhu 400°C selama 2 jam di pirolisis kedua. Manakala, penyediaan air sisa sintetik melibatkan penggunaan serbuk manganum sulfat menunjukkan reaksi tindak balas aktif berbanding penggunaan larutan piawai dengan kepekatan 1000 mg/L. Kajian ini menunjukkan peratusan penyingkiran mangan dari air sisa sintetik adalah sebanyak 33.55% pada pH 5 dan 0.8g PCFF, lebih tinggi berbanding peratusan penyingkiran mangan kajian terdahulu sebanyak 11.44% pada pH 5 dan 1.5g PCFF. Kajian ke atas karbon aktif telah dilaksanakan melalui SEM/EDX dan Raman Spektroskopi. Imej SEM menunjukkan permukaan PCFF-1 dan PCFF-3 adalah kasar berbanding permukaan PCFF-2 seterusnya menyediakan kawasan yang lebih luas bagi proses penjerapan. Walau bagaimanapun, keputusan Raman menunjukkan bahawa karbon aktif yang terhasil tidak mampu menjerap logam berat dalam air sisa dipengaruhi oleh faktor saiz liang karbon aktif, ketidaksesuaian karbon aktif untuk logam berat yang tertentu dan disebabkan oleh faktor caj permukaan karbon aktif. _______________________________________________________________________________________________________ The presence of heavy metal in wastewater pose to various negative impact on human health and environment. During the past decades, many attempt made to produce low cost adsorbent prior wastewater treatment for removing polluting ions such as calcium, zinc, magnesium, and manganese from industrial water systems. However, current activated carbon available are expensive but innovative effort and research now are moving forward towards the production of activated carbon with utilization of natural waste product such as chicken feather fiber. This alternative yet is a simple, low-cost, environmentally friendly for wastewater treatment. This study investigated the removal of heavy metal from synthetic wastewater using Pyrolyzed Chicken Feather Fiber (PCFF). PCFF act as an activated carbon derived from waste chicken feather produced from the two stage of pyrolysis method at 195°C for 5 hours and 400°C for 2 hours respectively.. The result obtained reveal that percentage removal of manganese in this study was 33.55% at pH 5 and 0.8g of adsorbent, higher than previous research with removal of 11.44% of manganese at pH of 5 and 1.5g of adsorbent. The activated carbon then are characterize by SEM/EDX and Raman Spectroscopy. SEM images showed that the surface of PCFF-1and PCFF-3 is rougher whereas the surface of PCFF-2 is smoother thus providing the larger surface area for the adsorption process. However, Raman analysis showed that produced activated carbon was unable to adsorb the pollutants due to the size of the pore presence in the activated carbon, unsuitability of activated carbon for the removal of selected heavy metal and due to surface charges.
