Chemiluminescence of aldehydes (like formaldehyde, acetaldehyde, propioaldehyde and benzaldehyde) and hydrohen peroxide in presence and absence of luminol has been studied. Magnesium hydroxide was chosen for solution making alkaline. The peak CL intensity initially increases with concentration, attains an optimum valu for a particular concentration then decreases with further increases in concentration of aldehydes. It is also observed that for all aldehydes maximum CL found for very low concentration (0.03M) of magnesium hydroxide. The CL intensity increases drastically in presence of 0.001M luminol and reaction becomes faster
