![]() ![]() Allow the beaker to stand for 20 minute.ġ)Taken above solution in digestion flask due to cause of distillation.Ģ)Added 50 ml NaOH(50%) in above solution.then sample neutralised.Ĥ)A stream of water vapour is bubbled into the sample to entrain the NH3 formed.ĥ)NH3 is captured in a 50 ml of Boric acid sol.Taken 49 ml test water sample ,added 1ml Nessler reagent in a beaker.In this process nesseler reagent act as main role in first step and in second step NaOH act as main role.Ĭhemicals:- Nessler reagent, NaOH (50%), Boric acid,Methyl red indicator. *#*For estimation of ammonia I followed combine process of colorimeter & kjeldiahl method. Readings:-Taken absorbance on colorimeter sr no Prepared solution by using following table and take absorbance on colorimeter. again take 1 ml solution from this solution and dissolved in 100ml distilled water.ĭissolved 24 gm sodium hydroxide pelletes in 100 ml distilled waterĭissolved 10 gm zinc sulphate heptahydrate in 100 ml distilled waterįor ammonia test need to draw graph for this take readings of given chemical ![]() Kept above solution 5 days in dark place after 5 days used this solution.ģ9.2gm EDTA, 20.72gm NaOH, dissolved in 100 ml distilled water.ĭry 1gm ammonium sulphate in oven at 100 degree celcius for 1 hourĪfter accurately weight 0.4718 gm of ammonium sulphate and dissolved in 100 ml distilled water. ![]() Procedure:- 1st I prepared solutions – Nessler reagent, EDTA, Ammonium sulphate,ġ0gm HgCl2 (mercuric chloride), 7gm KI(potassium iodide), 16gm NaOH (sodium Hydroxide) are dissolved in 100ml distilled water. I studied different method for estimation of ammonia in water and organic compound but here I selected one of the method for estimation of ammonia are as follow,ĭiagrammatic representation of kjeldiahl set up:. I had decided to work on this project,because fish mortality rate is gradually increases in aquaponics of vigyan ashram due to increase ammonia level in water.so I choose to do this project due to need of estimation of ammonia to solve this problem.Īim:- Estimation of percentage of ammonia by using kjeldahl process. Ammonia is excreted by animals and produced during decomposition of plants and animals, thus returning nitrogen to the aquatic system. If phosphate is not abundant it may limit algal growth rather than nitrogen. Nitrogen can be an important factor controlling algal growth when other nutrients, such as phosphate, are abundant. Nitrate predominates in unpolluted waters. Nitrate and ammonia are the most common forms of nitrogen in aquatic systems. Ammonia can be converted to nitrite (NO2 ) and nitrate (NO3) by bacteria, and then used by plants. The neutral, un- ionized form (NH3 ) is highly toxic to fish and other aquatic life.Īmmonia is the preferred nitrogen-containing nutrient for plant growth. Total ammonia is what is measured analytically in water.Īmmonia is also one of the most important pollutants because it is relatively common but can be toxic, causing lower reproduction and growth, or death. Total ammonia is the sum of both NH3 and NH4 +. Its chemical formula is NH3 in the un-ionized state and NH4 + in the ionized form. Ammonia is a nutrient that contains nitrogen and hydrogen. ![]()
