Abstract: A diffusive gradients in thin films (DGT) test device for lake water, including: a floating ball and a plurality of water sampling units. A DGT detection device, a water quality detection device with a multi-parameter probe, and a water sampling device are disposed in each of the water sampling units. The water sampling device includes: a plurality of sampling bottles, each of the sampling bottles is provided with an inlet pipe and an exhaust pipe, each of the inlet pipes and exhaust pipes is provided with a one-way solenoid valve; a peristaltic pump, a water sample outlet of the peristaltic pump communicates with the inlet pipes of the plurality of sampling bottles via a multi-way connector; the exhaust pipes of the plurality of sampling bottles are connected to an exhaust manifold via a multi-way connector; a control device connected with the peristaltic pump and each of the one-way solenoid valves.
