In this paper, a removal cations method is analysed by photocatalysis and is studied
the influence of different factors for silver removal. This work shows the effect
of various parameters on the removal reaction. In that sense, increasing of compound
such as alcohol is one of the most important and effective characteristics that could
be affect directly on photocatalyst mechanism and this has relation with the properties
of photocatalyst, that could produced a hole-electron in chemical reaction, and this
is vinculated with a change in the efficiency of reaction.
