The invention discloses a blood ion concentration detection device and method and a calcium ion concentration detection method, and belongs to the field of blood purification. Monochromatic light emitted by a monochromatic light source is divided into first monochromatic light and second monochromatic light; wherein the first monochromatic light passes through a blood pipeline and a first monochromator filter group in sequence and then is transmitted to a first optical signal converter; the second monochromatic light is transmitted to a second optical signal converter through a second monochromator filter group; then, the first optical signal converter and the second optical signal converter are used for converting light intensity signals into electric signals, and the controller calculates the blood ion concentration according to the Lambert-Beer law. According to the blood ion concentration detection device and method and the calcium ion concentration detection method, the ion concentration in the blood can
