Abstract

The invention relates to a potassium salt content detector. A determination bracket comprises a determination platform and a bracket which is arranged beside the determination platform; a sample weighing unit, a titration unit and a sampling unit are arranged beside the determination platform; the titration unit and the sampling unit are located at two ends of the determination platform respectively; a stirring unit, a filtering unit and a camera are arranged at the upper end of the determination platform. The potassium salt content detector provided by the invention has the advantages that the titration unit is arranged and can be used for automatically dropwise adding a needed solution into a sample cup, so that a phenomenon that a manual titration finishing point is unclear is avoided;furthermore, the camera is used for collecting colors, so that a hesitation phenomenon caused by manual judgment is avoided and the accuracy of a determination result is ensured.

Description

technical field [0001] The invention relates to the field of geological analysis, in particular to a potassium salt content detector. Background technique [0002] The determination of potassium salt content is carried out according to SY / T5503-2009. The rock sample is soaked and extracted in distilled water. After all the water-soluble potassium salt in the rock sample is dissolved in the extract, it is filtered to measure the chloride ion content in the extract, and then calculate Potassium content of rock samples. [0003] Data processing, see formula (1) [0004] [0005] In the formula: B - Potassium salt content, mg / Kg; [0006] C AgNO3 —concentration of silver nitrate standard solution, mol / L; [0007] V - the total volume of the extract, mL; [0008] V 3 - the amount of silver nitrate standard solution used when measuring samples, mL; [0009] V 4 - the amount of silver nitrate standard solution used when measuring the blank, mL; [0010] m - weigh the ma...
