Assessing antibiotic residue removal from milk using biochar

Abstract

The aim of this study was to evaluate the antibiotic residue removal from milk using biochar. The milk samples were collected from the local milk distributors of Coimbatore city and screened for antibiotic residues by using 3-1 Dip Stick which can screen the three major antibiotic groups like Beta lactam, tetracycline and sulfonamide. The present investigation analyses the methodology for removing antibiotics from milk using Prosopis wood biochar, Rice husk biochar and Coconut shell biochar at different temperatures and contact time. The results revealed that Prosopis biochar of 0.2 mm sieve size at higher temperatures subjected to 60 minutes contact time performed better and removed the antibiotics from a maximum number of milk samples.
