| dc.description.abstract | A study concerning the determination of the distribution patterns of heavy metals (Cu, Fe, Zn) in Siak River has been done using a spectrophotometer (AAS). This research used an experimental method that is focused on the study of the pattern of spread of heavy metals Cu, Fe and Zn. The process was started by taking samples at 5 locations, then filtered with Whatman 40 Filter 0,45 μm and added HNO3 to dissolve the metals contained in the water sample, further analysis was undertaken using spectrophotometer (AAS) to determine the absorbance of each metals in water sample and standard solutions. Based on the data of standard solutions. Regression curves can be set up to determine the concentration of each metal. Results of water sample analysis showed that the concentration respectively of Cu, Fe and Zn was 0,0147 ppm, 0,0239 ppm and 1,9854 ppm. Based on water quality standards released by Unit Pelaksana Teknik Pengujian Dinas Pekerjaan Umum Provinsi Riau, the concentration of Cu and Zn contained in the Siak river water samples are safe for consumption for the maximum allowable limit, there are 0,02 ppm for Cu and 0,05 ppm for Zn. Another case with the Fe concentrations, that exceeds the maximum allowable concentrations for drinking in the amount of 1,9854 ppm from 0,3 ppm. After assessment, the safety distance to use the water of Siak River is more than 24,5 meters from the source of the waste | en_US |
