| Summary: | Due to the environmental issue that have become serious each day, many researchers
interested to solve the problem with few method of water treatment including carbon
adsorption, ultrafiltration, coagulation using chemical method, biodegradation using microbes,
ozonation and also advanced oxidation process. One of the popular methods is using doping
method. The photocatalytic activity is said to be directly proportional to the dopant
concentration based on previously study. The optimum photocatalytic activity will occur at
optimum dopant concentration, but at certain level of dopant concentration, the photocatalytic
efficiency will be decreasing. DR-UV Vis analysis shows that the nitrogen and magnesium
doped caused the formation of new mid-gap energy state and make the band gap shifted. |
