oxide(H2O2), a hydroxide (OH-). In order to produce a strong glow, they need a catalyst to accelerate the process. The catalyst in this case is the iron in hemoglobin . If hemoglobin and the luminol mixture come in contact, the iron in the hemoglobin accelerates a reaction between the hydrogen peroxide and the luminol. In this oxidation reaction, the luminol loses nitrogen and hydrogen atoms and

1. Introduction of POSCO
Pohang Iron & Steel Company (POSCO) was founded in 1968. PARK Tae-joon led the whole establishing process and became a first CEO of the company. It was due to the ‘special’ relationship with ex-president PARK. The money invested by the Korean government was provided by Japan and US as loans and grants. Compensation payment for colonial rule damages of Japan also inv
2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) water purification began with the Egyptians. It is said that impure water should be boiled over a fire, heated in the sun, have a hot iron dipped into it or purified by filtration through sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m
