Considering the high importance and the threats of the presence of elements in concentrations excessive levels in drinking water, the optimal limit and permissible limit In drinking water In each country is determined. One of the possible elements In drinking water is Boron, The presence of Boron can cause blood clots and stimulate the eye and cause nausea and vomiting and diarrhea. In this research, element content of some water resources used in a number of villages around the city of Urmia were investigated, and identified that most of the elements are virtually desirable, and only the Boron element in some sources is more than allowed. Hence, by stabilization of nanoparticles on activated carbon Using a thermal method, a new nano-absorbent was designed, and to increase the efficiency, tungsten oxide nanoparticles was used. Optimal values, including pH=7.8, absorbent weight 0.07 grams, Collision time 20 minutes, and temp. 40-60 oC has been reached. The removal efficiency was 82% and by partial washing and reuse, efficiency is maintained at an acceptable level. Considering the high capacity of this adsorbent and the concentration of Boron element in the studied resources, utilizing very low amounts of this adsorbent, the amount of Boron element in the studied sources has reached the standard limit of drinking water.
