Method for rapidly determining content of calcium carbonate and fiber in cigarette paper white water

The invention discloses a method for rapidly determining the content of calcium carbonate and fiber in cigarette paper white water, which comprises the following steps of: performing full-wavelength scanning on calcium carbonate and fiber standard suspension with known concentration by using an ultraviolet-visible spectrophotometer and establishing a corresponding standard curve; and detecting diluted white water under a cigarette paper production line net by using an ultraviolet-visible spectrophotometer, carrying out acidolysis treatment on a white water sample by using acid, detecting the sample subjected to acidolysis by using a photometer, inputting an absorbance value at a specific wavelength of the sample into a standard curve by using a difference method, and calculating the content of calcium carbonate and fiber in the white water sample. The method is good in accuracy, high in precision and high in analysis speed, a set of on-line monitoring platform can be designed based on the method, real-time on
