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.

1.2.1 EXPLANATION OF BIOCHAR
Magnetic biochar is a recently new in the research line which has been divided into four broad parts to this thesis: the explanation of biochar and why it is interesting, explanation of how biochar is produced, current and potential future uses of biochar and the why magnetic biochar is interesting and the science behind it .
Biochar is a new substance which is found in soils around the globe which is due to deposition by environmental events which are high in areas, west of the Mississippi River and by the eastern side of the Rocky Mountains which most of the productive fertile soils in the world are located. Historically, biochar usage goes way back to two thousand years, in the Amazon basin there is evidence that biochar is found in fertile soils which is known as “Terra Preta and Terra Mulata” which means “Dark Soil” in Portuguese was made by ancient amazon cultures and because of the huge quantities of biochar which was found in soils, the area is still very much fertile due to the increase rate of leaching due to rains. Also in Asian regions of the world, biochar use in agricultural processes has an ancient history which recently as created favourable farming systems and techniques (Hunt, et al., 2010).
