INTRODUCTION
Antibiotics are prescribed for the treatment of an infection caused by bacteria, fungi and parasites
Kill bacteria by destroy the structure of their DNA Antibiotic -Metronidazole (MET).cause -vomiting, fever, joints pain..etc.Antibiotic cause problem in environment and human life.

OBJECTIVES AND STUDY
Remove MET from aqueous system by means of adsorption process.
Efficiency of the adsorbents in removing MET. Effect of -pH and contact time. Removal of MET using. PAC TiO2
Concrete contain graphene

Three of the primary sources of antibiotics entering the environment Medicine Agriculture (both livestock and produce). Pharmaceutical processing plants dumping drugs
into wastewater.

ADSORPTION
Adsorption is physico-chemical method is an attractive and effective method for antibiotic removal .

Equilibrium study
Adsorption Isotherm is used to find the maximum adsorption capacity
o Langmuir isotherm o Freundlich isotherm
MET Concentration varied 1,5, 10, 25, 50, 100 mg/L
Adsorbent dose: PAC:1 g/L, Concrete containing graphene: 10g/L

PAC and CONCRETE The maximum adsorption capacity of PAC and
graphene coated concrete for MET removal was 3.48 mg/g and 0.18 mg/g
PAC has shown nearly 98% removal (from 10 mg/L to 0.02 mg/L) with in 1 hr
Concrete with a dosage of 1, 10 and 20 g/L as shown of MET removal of 13.5, 15.5 and 19.7%, respectively

CONCLUSION
PAC fit in to Freundlich isotherm Its is a good adsorbent to remove MET from
wastewater PAC is multi pollutant adsorbent Some of new adsorbent can be under go kinetic
study and isotherm
