Abstract

The invention discloses a separation and extraction device for water quality alkyl mercury detection. The device comprises a supporting frame provided with a workbench, a rotating frame driven by a power device is rotationally installed on the workbench, and at least two sulfydryl cotton pipes are located and installed on the rotating frame; the device further comprises a lifting driving element arranged on the supporting frame, the lifting driving element drives a lifting frame, the lifting frame is located above the sulfydryl cotton tubes, a water sample funnel and a desorption solution funnel which are communicated with the positive pressure mechanism are arranged on the lifting frame, the water sample funnel and the desorption solution funnel correspond to the sulfydryl cotton tubes respectively, and a residual liquid collecting cup and an analytical release liquid cup are respectively arranged below the sulfydryl cotton tubes. Positive pressure is applied into the water sample funnel and the desorption solution funnel, so that the flow velocity of a water sample and a desorption solution is increased, the working efficiency is improved, alkyl mercury in the water sample can beuniformly and fully adsorbed by sulfydryl cotton, the loss rate of the alkyl mercury is reduced, meanwhile, the problem that desorption release solution remains on sulfydryl cotton can be effectivelyavoided, and the precision of a detection result is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of water quality detection aids, in particular to a separation and extraction device for water quality detection of alkylmercury. Background technique [0002] At present, the method of separating and extracting water samples is as follows: the water samples are placed in a separatory funnel, the lower end of the separatory funnel is connected to a mercapto cotton tube, and the bottom of the mercapto cotton tube is arranged in a residual liquid collection cup. When the sample flows through the mercapto cotton tube, the mercapto cotton will absorb the alkylmercury in the water sample, and the raffinate will flow into the raffinate collection cup for collection, and then add the analytical solution into the mercapto cotton tube, and The alkyl mercury adsorbed by the mercapto cotton is dissolved again, and then the dissolved analytical solution is subjected to subsequent treatment, and finally detected by gas c...
