Beschreibung
Master's Thesis from the year 2011 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, grade: 3.32/4, University of Teesside, course: Environmental Technology, language: English, abstract: Magnetic biochar which is made from agricultural biomass waste such as SRC willow which is a densely planted, increased yielding form of energy crop which is the leading sources in renewable energy production, mixed with iron (II) chloride and iron (III) chloride is known as a multi-dynamic material for land remediation and agricultural uses. Two magnetic biochars (1,0 M iron solution magnetic biochar and 0,1 M iron solution magnetic biochar) were prepared by the chemical mixture and co-precipitation of iron (II) chloride tetrahydrate and iron (III) chloride on SRC willow with particle size of less than 2mm and the mixture of SRC willow with iron (II) chloride tetrahydrate and iron (III) chloride is dried in the oven and subsequently pyrolysed at a temperature of four hundred degrees celsius which led in iron solution magnetic biochar preparation. Scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction analysis were done on the 1.0 M iron solution magnetic biochar and 0.1 M iron solution magnetic biochar depicts a large amount of iron compounds in the 1.0 M iron solution magnetic biochar than in the 0.1 M iron solution magnetic biochar. Ultra-violent infrared spectrometry done on iron (II) chloride tetrahydrate, iron (III) chloride and copper (II) sulphate pentahydrate; atomic absorption spectroscopy and ultra-violent spectrometry was done on copper (II) sulphate pentahydrate and deionised water mixed with 1.0 M iron solution magnetic biochar, 0.1 M iron solution magnetic biochar and activated charcoal nitrot. For copper (II) sulphate pentahydrate solution, 0.1 M iron solution magnetic biochar has a higher adsorption capacity than the 1.0 M iron solution magnetic biochar for Atomic absorption spectroscopy. For ultra-violent infrared spectrometry, the adsorption capacity for 1.0 M iron solution magnetic biochar is higher than the 0.1 M iron solution magnetic biochar.
