Homogeneous Liquid-Liquid Microextraction via Flotation Assistance Method as a Sensitive and Efficient Sample Preparation Method for Determination of Diazinon in Water Samples

In the present study a sensitive method for extraction of diazinon in water samples was developed using homogeneous liquid-liquid microextraction via flotation assistance (HLLME-FA). Toluene at microliter volume level was used as extraction solvent. The main advantages of method are high enrichment...
