Abstract
Around (25) sewage samples were collected in different seasons: Summer (June), Autumn (October and November), Winter in (December) 2013 and (January) 2014) from Nawroz quarter – Erbil city. Calorimetric method was used to determine the phosphate concentration, using ammonium molybdate as color indicator reaction procedure. The results were read on spectrophotometer at λmax = 570 nm. The values estimated under the standard curve, the results shows a variation in the recorded values between the different seasons that goes less, within and more than the world recognized standard values.
