It is attempted in the present investigation to study the residence time distribution of electrolyte in a continuous stirred tank electrochemical reactor. The electrolyte flow behavior has been experimented on by using both pulse and step input techniques. The exit age distribution curves obtained under various operating conditions are critically analyzed. A theoretical model based on tanks in series has been developed to describe the electrolyte flow behavior inside the continuous stirred tank electrochemical reactor, and the model simulations are validated with experimental observations.

Problem statement:The occurrence of endosulfan, carbendazim, chloropyripos in 10 banana samples in southern area of Tamilnadu, India (hill banana, karpuravalli, monthan, nendran, ney poovan, pachanadan, poovan, rasthali, red banana, robusta) was investigated. Approach: In 7 samples, Carbendazim was found at concentrations ranging from 0.002-0.11 mg kg −1 . In three samples, carbendazim was not found, whereas endosulfan, chloropyripos was not detected in any sample. Results: Analysis was carried out using HPLC-UV and samples were confirmed by GC-MS.
