Target Antibiotic Classes: Understanding Polarity and pKa Ranges Developing an effective SPE method for trace antibiotic detection in wastewater begins with understanding the physicochemical properties of target compounds. The three major antibiotic classes—sulfonamides, fluoroquinolones, and macrolides—exhibit diverse polarity and ionization characteristics that directly influence SPE retention and elution strategies. Sulfonamides Sulfonamide antibiotics typically contain an […]

Trace Pesticide Contamination Concerns in River Water River water monitoring for trace pesticide contamination represents one of the most critical environmental analytical challenges facing regulatory agencies and research institutions today. Pesticides, even at sub-part-per-billion (ppb) levels, can have profound ecological impacts, affecting aquatic life, disrupting ecosystems, and potentially entering drinking water supplies. The analytical challenge
