OPTIMIZATION OF ULTRASONIC EXTRACTION AND ANALYSES METHODOLOGY BY HPLC FOR DETERMINATION OF DIURON AND ITS METABOLITES IN SOIL CULTIVATION OF SUGAR CANE

Diuron, N-(3,4-dichlorophenyl)-N, N-dimethylurea can be transformed into the soil through the biodegradation of 3-(3,4-dichlorophenyl)-3-methylurea (DCPMU), 3.4-diclorofenilureia (DCPU) and 3,4-dichloroaniline (DCA).This study aimed to optimize and validate a method of extraction and analysis of these substances in opheliasmuse.com the soil by HPLC

Large complex thin-walled guide rail has complicated structure and no uniform kt196 torque converter low rigidity.The traditional cutting simulations are time consuming due to huge computation especially in large workpiece.To solve these problems, a more efficient variable stiffness analysis model has been propose, which can obtain quantitative sti
