Faculty of Science has held a seminar on green chemistry, in which Head of the Chemistry Department, Prof. Dr. Lama Majid Ahmed, has presented it.
Dr. Lama Majid says that the lecture clarifies the meaning of green chemistry and its use in clean technologies that are less dangerous to health or environment or have no effect, indicating that this term appeared at the beginning of the nineties of the last century.
Dr. Lama Majid adds it has 12 principles, which focus on how to reduce and recycle the waste generated during the preparation of chemicals through processing or using environmentally friendly materials, as well as photochemistry of the types of this chemistry, which are without side reactions and lead to the transformation of dangerous and toxic substances into friendly materials. The environment or creating a balance in the environment through the use of light or sunlight to produce solar cells and electrochemistry fall within the categories of techniques for green chemistry.
Majid explains that the use of plant extracts to prepare nanocomposites without resorting many chemicals is done by using natural materials found in leaves, flowers, seeds or roots of plants.
