C. producing reactive carbon species
D. producing reactive fluorine species

B. producing reactive oxygen species
C. Biodegradable substances
D. producing reactive fluorine species
3. Which is not dark AOP
A. Ozone
B. Fenton
C. Electrolysis
D. Photolysis
4. Which is light-driven AOP
A. Ozone
B. Fenton
C. Photo-Fenton
D. Photolysis

Answer 1

Q1. Ans) (B) producing reactive oxygen species

As the full form suggests, AOP cane be described as a set of chemical reactions conducted to erase organic and inorganic materials in water and wastewater by oxidation for the production of hydroxyl radicals (·OH)

Q2. Ans) (B) producing reactive oxygen species

AOP has a tendency to convert pollutants or contaminants into water, carbon dioxide, or any suitable oxygen species via oxidation.

Q3. Ans) (C) Electrolysis

Conducting AOP in the absence of energy is indeed difficult, if it involves the usage of Electrolysis.

Q.4 Ans) (D) Photolysis

As the name suggests, photolysis plays an important role in conducting AOP with the help of light

Answer 2

From question no 1. The answer is producing reactive oxygen species

Explanation:

• An unavoidable consequence of aerobic metabolism is the production of reactive oxygen species (ROS). ROS include free radicals such as superoxide anion ( O ₂₋), hydroxyl radical (•OH), as well as nonradical molecules like hydrogen peroxide (H₂O₂), singlet oxygen (¹O₂), and so forth.

From question 2, the answer is Producing reactive oxygen species.

Explanation:

• ROS are a group of free radicals, reactive molecules, and ions that are derived from O₂. It has been estimated that about 1% of O₂ consumed by plants is diverted to produce ROS.

From question 3, the answer is photolysis

Explanation:

• Photolysis is part of the light-dependent reaction or light phase or photochemical phase or Hill reaction of photosynthesis. The general reaction of photosynthetic photolysis can be given as H2A + 2 photons (light) → 2 e− + 2 H+ + A. The chemical nature of "A" depends on the type of organism.

From question 4, the answer is photolysis

Explanation:

• Photolysis (also called photodissociation and photodecomposition) is a chemical reaction in which an inorganic chemical (or an organic chemical) is broken down by photons and is the interaction of one or more photons with one target molecule.
