3.3 operating procedures3.3.1 steps for designing experiments In an experiment to study the dye removal using nZVI required BBD. In an experiment designed to make more easy color removal test RR-159, which can be divided into three trials. The experiment as follows: 3.3.1 unchecked syllables nZVI synthesis. Using water as the solvent DI FeCl3 3.3.1.2 nZVI synthesis. Using Alcohol as the solvent Ethyl FeCl 3 3.3.1.3 the synthesis of Isopropyl Alcohol using nZVI solvent FeCl 3.3.3.2 preparation of iron Nano-saronuphak ** (nZVI) 3.3.2.1 weighing NaBH4 0.756 g dissolved DI 40ml Iron (III) Chloride weighing 3.3.2.2 Hexahydrate 0.4865 g. Solubility in solvents of different using water, Ethyl Alcohol and Isopropyl Alcohol DI, volume 40 ml. 3.3.2.3 prepare perfect pump for slurry containing sottan ZiLOG NaBH4 into agitator slurry Fecl 3 using Rev 1 s/mL. 3.3.2.4 used magnetic iron that fall at the bottom of the beaker. 3.3.2.5 brought Syringe Extraction solvents which are in the beaker until all Nano-iron particles, just. 3.3.3 ** experiment procedure and performance studies to get rid of the stain, using nZVI.3.3.3.1 the slurry preparation RR-159 5000 ppm concentration volume 500 mL, then pouring it into Nano-iron particles.3.3.3.2 lead a beaker containing solvents, RR-159 and nano-iron particles with froi and insert agitator slurry *3.3.3.3 timer stirring slurry 3.3.3.4 substance samples at 0-120 minutes.3.3.3.5 leading to filter air filter Kit Syringe Filters for iron krongonuphak Nano. 3.3.3.6 bring the dye to measure the intensity of color with a UV spectrometer at a wave length 512. NM Again to find dye removal using nZVI 3.3.3.7 Calibration Curve graph and values lead * the intensity of the colors used in the c/c fishing rough phlo 0 time with analysis and discussion results 3.3.3.8 * experiment with statistical methods to determine the performance of a Nano-iron particles, dio.
