| Abstract: | The paper studied and set up a methad of determaining K20 in K2SO4 and KC1 by using C4 glass pot to filtrate four benzene boron potassium deposition and nficrowave heating to constant weightiness, but not using formaldehyde in the process, Through the experiment, some conditions were obstained that the microwave power was 300W, the time of heating and drying to constant weightiness was 6 minites. The method was time - saving, simple, utility and no poisonous harm, according with produce requirement. |
