Gravimetric Determination of Phosphorus in Fertilizer Samples ------------------------------------------------- Results and Discussion More than 50% of fertilizers are composed of nitrogen‚ phosphorus and potassium because these three nutrients are essential but are deficient in soils. To ensure good quality of fertilizers‚ it is significant that the amounts of these nutrients are quantified. In this light‚ gravimetric principles are of much use. The objective of the experiment is to determine

emulsified grease or oil amount in the water samples by utilizing from the partition-gravimetric method. Introduction: Oil and grease is an important parameter for water quality and safety. Regulatory bodies worldwide set limits in order to control the amount oil and grease entering thewater reservoirs or the sea through industrial discharges and also limit the amount present in drinking water. The partition – gravimetric method involves extraction of dissolved or emulsified oiland grease from water
