The invention discloses a method for quickly determining low-content molybdenum in a solution. The method comprises the following steps: performing color development treatment on molybdenum solutionswith different known concentrations by using a sodium sulfide solution so as to obtain colorimetric cards with different colors; and then carrying out color development treatment on a to-be-tested solution with an unknown concentration by using the sodium sulfide solution, and comparing a color development result with the colorimetric cards so as to obtain the content of molybdenum in the to-be-tested solution. The method of the invention can quickly determine low-content molybdenum in a solution, is simple to operate and can be directly used for on-line qualitative detection in an industrialproduction site. 本发明公开了种快速测定溶液中低含量钼的方法，所述方法是使用硫化钠溶液对不同已知浓度的钼溶液进行显色处理，获得具有不同颜色的比色卡，之后使用硫化钠溶液对未知浓度的待测钼溶液进行显色处理，与比色卡对比得到待测钼溶液中钼的含量。本发明的方法能快速测定溶液中低含量的钼，操作简单，可直接用于工业生产现场的在线定性检测。
