Water quality sulfide acidification blowing instrument

Water quality sulfide analyzer

一、 HS-4SYWater quality sulfide acidification blowing instrumentProduct Introduction:

Developed and produced according to the standard GB/T16489-1996 for the determination of sulfides in water quality - Methylene blue spectrophotometric method (iodometric method). Meet the sample pretreatment requirements for sulfide determination in water quality. Suitable for the determination of sulfides in surface water, groundwater, domestic sewage, and industrial wastewater. This product has the characteristics of easy control, simple and fast operation.

2、 Execution standards:

GB/T16489-1996 "Determination of Sulfides in Water Quality - Methylene Blue spectrophotometric method"

HJ/T600-2000 "Determination of Sulfides in Water Quality - Iodometric Method"

The State Environmental Protection Administration compiles the "Monitoring and Analysis Methods for Water and Wastewater (Fourth Edition)"

3、 Characteristics:

1. Large capacity reaction bottle, capable of processing multiple samples simultaneously.

2. The three ports of mouth, gas inlet, and outlet are integrated and independent of each other, and the operation will not interfere.

3. Constant temperature water bath heating, equipped with a fast automatic constant temperature control system, and the heating temperature can be manually set.

4. The sample rack and gas distribution system are adjusted by a fixed knob for lifting and rotating the sample rack. The sample is installed on the front for easy operation.

5. The nitrogen flow rate of each sample is independently controlled and adjusted or closed, and the needle valve gas flowmeter accurately controls and displays the total gas consumption.

4、 Instrument principle:

The sulfides in the water sample are acidified, and the generated sulfur ions enter the absorption bottle/absorption color tube with the carrier gas (ammonia) and are absorbed by the absorption solution (zinc acetate sodium acetate solution). The corresponding analysis method is selected to analyze and determine the sulfur ions absorbed in the absorption bottle/absorption color tube.

5、 Technical parameters:
