are you smoke?

the risk if you smoke

you will lose a lot money if you smoke, illustration if you smoke one pack of cigarettes a day at $2.00 per pack, you spend $730 per year. If your habit has continued for a period of 20 years you will have spent an incredible $14,600! If you smoke two packs for that same period of time, you will spend $29,200!

You will be twelve times more likely to die from lung cancer. ten times more likely to die from some form of lung disease. ten times more likely to die from cancer of the larynx. six times more likely to die of heart disease. twice as likely to die of a stroke.

not only for your health, you also help your friends and human around you to die, yes you help them to die faster

Titanium dioxide to degrade pentachlorophenol

Titanium dioxide to degrade pentachlorophenol

Titanium dioxide to degrade pentachlorophenol

Pentachlorophenol is a phenolic compound that was chlorinated. Pentachlorophenol very toxic for our breath, cause dermatitis on skin and more toxic than inorganic solvent.

Pentachlorophenol waste almost dissolvable in water so degradation process is very hard. Some ways have been done to solve biological waste problem, but not efficient enough. For example, active carbon just involve pollutant absorption without decomposition process. Chemical oxidation process can’t decomposition all of organic compound be carbon dioxide and water, and have been used in high concentration waste.

Many century ago, scientist success to describe phenomenon photocatalytic in surface of metal-oxide semiconductor. Firstly, have been issued by Renz in 1921 until 1960, and not responding by scientist. Photocatalytic semiconductor popularity increase since publication Akira Fujishima in Nature magazine was issued in 1972. He was reported decomposition water be oxygen and hydrogen used single crystal TiO₂ with input UV light in low energy.

First research, TiO₂ have been used as photocatalytic suspension system. Nowadays, the uses TiO₂as photocatalytic is used in thin plate shape, which is immobilization TiO₂to many kinds of supported material like fiber, glass, silica, and titanium plat.
