![]() ![]() The only ions present were ammonium and fluoride ions in which their concentration were also below the standards recommended by WHO in 2014.These water samples collected from different sites in MUSANZE and NYABIHU Districts, should be accepted as drinking-water after manual addition of some important ions like chloride to kill micro-organisms and others needed by our body to improve their quality. Based on analysis done in laboratory, these water samples do not contain any chloride, zinc, manganese and iron ions. In this session, different ions like chloride, ammonium, fluoride, zinc, manganese and iron were analyzed in water samples. We know that Water is one of the most important and abundant compounds of the ecosystem and all living organisms on the earth need water for their survival and growth. In third session of this internship, I worked on analysis of water. Essential oils are very useful in different domains due to their chemical constituents such as terpenes, alcohols, flavonoids, fatty acids, steroids, etc. As results for this session, we found that many essential oils were produced by eucalyptus macurata with a yield of 1.39%, and 0.984% for eucalyptus globulus. Secondly we worked on extraction of essential oil from the fresh leaves of two types of eucalyptus eucalyptus globulus and eucalyptus macurata by using hydrodistillation method. This implies that, the groundnuts are good for production of a large amount of oil than soybeans. Firstly, we focused on extraction of fat and oil from natural products as soybeans and groundnuts using soxhlet extraction method, here the yield were 45.128% and 21.961% of groundnuts and soybeans respectively. The period of internship was one month, that is from 2nd to 31st July, 2015 and it is mainly made with two activities: Extraction of oils and Water analysis. The Chemistry Department planed the internship of students for the main objective of allowing them to be familiar with practical knowledge based on the theory learned in class and make appropriate application of what they studied during the previous academic years. ![]()
