Sažetak
Determination of phosphor and other nutritive supstances in waste water samples is important for enviroment chemistry. Concentration of phosphor must be under 0.01 mg/L for clean water and several mg/L for waste water. Waste water loaded with nutritive supstances indicate a possibility of eutrofication. A waste water were only mechanical treatment and like that realise in sea. Spectrometric method were used for analysis with tin(II)chloride act like reduce agent. For estimating of analysis accuracy we used a statistic method for data edit. A parameter wich was editing: medium concentration value, standard deviation, lowest concentration value, maximum concentration value, median and deviation coefficient.
