【Abstract】 A kind of quick determining method of nitrite in water was offered.The method is easy to operate.The optimal conditions are the peak absorption wavelength equals to 524 nm and the mol light absomtion coemcient equals to 3.27 ×10 4L/mol·cm.The method was applied to the determining of the nitrite in Qing Shang Lake,and When the water sample was added the standard sample,the recycle rate was 96.90±2.07%.更多还原
