Hybrid materials in the removal of diclofenac sodium from aqueous solutions: Batch and column studies

Abstract

Hybrid

materials

(AAS

(Al-AMBA-sericite

and

AHS

(Al-HDTMA-sericite))

was

obtained

and

materials

are characterized

by

XRD,

SEM

and

IR

analytical

techniques.

Hybrid

materials

were

assessed

for

efficient removal

of

diclofenac

from

aqueous

solutions.

Increasing

the

diclofenac

concentration

(1.0

to

20.0

mg/L) and

pH

2

to

7

favored

greatly

the

removal

of

diclofenac

by

AAS

and

AHS.

Background

electrolyte concentrations

from

0.0001

to

0.1

mol/L

NaCl,

insignificantly

affected

percent

removal

of

diclofenac.

The breakthrough

results

were

fitted

well

to

the

Thomas

equation

and

hence,

loading

capacity

of

diclofenac was

found

to

be

0.561

and

1.056

mg/g

for

AAS

and

AHS,

respectively.
