In this study, the photodegradation and the mineralization of a cationic dye Methylene Blue (MB) from aqueous solution was investigated, in the presence of hydrogen peroxide, using a photocatalyst based on copper modified natural zeolite (Z-Cu). Comparative studies of photolysis, photocatalysis on the monocationic form of zeolite (Z-Na) and photocatalysis on Z-Cu, quantified in terms of process...

for the whole 20th century, bovine tuberculosis (btb) challenged the international community efforts to control this zoonotic disease. asia and africa accommodate the largest btb-infected zebu cattle in the world. similar to other few asian nations, iran has been actively running its btb-control plan for the last four decades. btb however, is still a number-one health concern for iranian veteri...

Triton X-100 is one of the most widely-applied man-made non-ionic surfactants. This detergent can hardly be degraded by biological treatment. Hence, a more efficient degradation method is indispensable for the total mineralization of this pollutant. Application of heterogeneous photocatalysis based on a TiO₂ suspension is a possible solution. Its efficiency may be improved by the addition of va...
