Abstract
Abstract The concentrations of some trace elements coblat, nickel, lead, mercury cadium, copper and Iron as well as PH value and the conductivity were derermined in the samples of water which in put and out put (waste) from AL-Daiwaniya textile factory and the effect of it on the AL-Daiwaniya river water which is nearest from the factory through one month .The concentrations of above elements were determined in the samples by two motheds. The flame Atomic absorptuon spectrophotometery and the spectrometery mothed which is sutiable for each ion and making Analytical comparative between them from some analytical values like correlation coefficient(r) ,relative standard error Erel% ,recovery value Re% and relative standard deviation RSD% for each ion. It is found that the frist mothed is more accurcy for measuring the all elements concentrations excapt measuring of Iron. From resultes we show that the Lead element is more concentration among other elements which was the middel concentration was (3.3ppm).The coblat element is less concentration from other elements which was the middel of it concentration was (0.043ppm) in the waste water samples and other elements have concentration between them in the different samples.We shown the increasing on the acidity and Conductivity for waste samples as comparative with the other samples which were PH between (6.5-7.2) and the Conductivity from the instrument directly in between (1210-1913)ms/cm and the measuring was making at the room temperature .
