Sodium naphtionate powder
Sodium Naphtionate powder
APPLICATIONS
In the field of hydrology, appreciated for its spectral properties and low coloration, Sodium Naphtionate is a tracer (optical brightener) widely used for mapping underground watercourses, checking hydraulic connections, transit and flow time studies, river flow measurements, seepage water path studies, checking the watertightness of layers, simulating the spreading of liquid substances, etc.
