Removal of Colour from Textile Dyeing Effluent Using Temple Waste Flowers as Ecofriendly Adsorbent
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 6
Abstract
In the present investigation easily available raw material, temple waste flowers(TWF) were used as ecofriendly adsorbent for removal of colour from textile dyeing effluent. The activated carbon from temple waste flowers were prepared by direct pyrolysis process, sodium sulphate (Na2SO4) and potassium hydroxide (KOH) process respectively and also physico-chemical parameters including pH, conductivity, moisture content, ash content, volatile content, fixed carbon, bulk density, porosity, specific gravity, water soluble matter, acid soluble matter, iodine number, methylene blue number, yield and Brunauer-Emmett-Teller (SBET) surface area of activated carbon were analyzed and compared. The structure, surface morphology and chemical compositions of carbon were determined by Field emission Scanning Electron Microscopy (FeSEM), and Energy Dispersive X-ray Spectroscopy (EDS) respectively. The prepared activated carbon is utilized for the removal of colour from textile dyeing effluent at different adsorbent dosage and contact time. Also the physico chemical parameters of textile effluent such as colour, pH, total hardness, biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), total suspended solids (TSS), turbidity, chlorides, sulphides, silica, calcium, iron, oil and grease were analyed. The results of the analysis were correlated with the water quality standards of BIS (Bureau of Indian Standard). The maximum colour removal efficiency of activated carbon was found to be 98.17% at 200 mg dose of adsorbent at normal pH and temperature conditions.
