An Investigation on the Effectiveness of Prepared Activated Carbon from Lignocellulosic Waste (Groundnut Shell) on the Decolourization of Fish Sauce Thwe Linn Ko Khin Yadana Win Mu Mu Naing Kay Khaing Hnin Moh Moh Zin The present research work focused on the extraction of natural dye from Mangosteen peel (Garciniamangostana Linn). The physico-chemical properties such as moisture content, ash content, total solids content and pH of Mangosteen peel were determined by association of official Analytical Chemists (AOAC) method. The chemical compounds present in Mangosteen peel were investigated by phytochemical tests. Natural dye was extracted from Mangosteeen peel with pure water at 70ºC for 60 minutes. The physico-chemical properties of extracted natural dye were also determined by AOAC method. An attempt was made on the dyeing of cotton fabrics using extracted natural dye with three different mordants such as zinc sulphate, potassium dichromate, potash alum and three different dyeing methods such as pre-mordanting, post-mordanting and simultaneous mordanting and different dyeing methods on the properties of dyed cotton fabrics were also investigated. Moreover, washing and rubbing fastness properties, staining and colour change of dyed cotton fabrics were assessed by using standard Grey scale. 2016 http://hdl.handle.net/20.500.12678/0000000866 https://meral.edu.mm/records/866
