Question

Zeolite are useful for environment because Select one O a. they are highly hydrophobic b. they are highly hydrophilic c. they are good for filtering the contaminants d. they can react chemically with the pollutants which statement is not true about nanomaterials and water Select one a, nanomaterials decontaminate water from pollutants bi nanomaterials can detect contaminants in water d. nanomaterials can desalinize water dinanomaterials absorb contaminants in Previous page Next pa a

Answer 1

1)

Zeolite is a mineral that has unique adsorption properties; it adsorbs a variety of heavy metals and ammonia, in their pores which allows it to remove a wide range of pollutants.

Hence they act as filter for water contaminants.

Option C

2)

Nanomaterials are chemically inert and possesses versatile hydrophilic surface chemistry. These properties make them for usage as a membrane and filter in water purification systems to remove bacterial and chemical contaminants from polluted water.

Hence option A
