纳氏试剂光度法测定氨氮影响因素的探讨
摘要:氨氮以游离氨或铵盐形式存在于水中。测定氨氮的方法通常有纳氏比色法、气相分子吸收法、电极法等。纳氏试剂比色法有操作简便、灵敏等特点。本文提出用纳氏试剂光度法测定氨氮的常见问题及解决方法。
Pay reagent luminosity follows the investigation and discussion abstract determining ammonia nitrogen influencing factor: The ammonia nitrogen there exists Yu Shui Zhong in form with free ammonia or ammonium salt. The method determining the ammonia nitrogen has generally pay than color law , the gas appearance molecule absorb law , electrode law etc. Mrs.Pay reagent handle characteristics such as simple and convenient , keen than color law has. The main body of a book is accepted bringing forward use reagent luminosity follows common problem and solution determining the ammonia nitrogen.

1. Power Switch Function is on / off controller working power source. 2. Amplitude modulator Is used to control the waveform duty cycle to regulate its function is within a certain range to change the vibration amplitude plating on the plating speed from micro-adjustment feature. 3. Velocity regulator Waveform is used to control the frequency of adjustment, the main function is to adjust speed plating. 4. Insurance Block 10A - Output DC insurance seat, when the overcurrent protection for the components used. 5. 6 terminals Input for the power supply, while the output control signals to the vibration plate machine. 6. Wiring diagram of the external terminals 6 Figure (D). 五. Instructions 1. Ensure that the vibration plate machine power input line is correct, the normal power supply, reliable, vibration plate fixed to the scaffold; 2. For the first time use, should be amplitude and velocity regulator scale are transferred 0. 3. POWER pull the power switch to the ON state. 4. With adjustable speed and amplitude adjustment potentiometer, so that plating velocity in the setting / best condition for continuous vibration plate. Note: in the regulation of speed and amplitude adjustment potentiometer, the first edge of the potentiometer a small black body, (called "lock potentiometer settings" button), counter-clockwise to set the drawing state, before they can be carried out on the potentiometer setting and regulation. Adjust to normal, we should "lock potentiometer settings" button in a clockwise direction pulling the lock to ensure that it does not out technical errors, otherwise set the parameters of the drift due to the quality of products would be adversely influence, and in severe damage to the machine so that vibration plate. 5. Shutdown / or stop the vibration plate when the POWER dial directly to the power switch to the OFF position, cut off the power supply controller can be. 六. Fault Detection 1. No vibration, and the power switch POWER indicator light does not shine. Approach: Are there any power supply; DC fuse is blown. 2. No vibration, but the power switch POWER indicator light. 3. Approach: 1) Check the scale of the amplitude modulator is greater than 4. 2) Check the e-board, components, and whether there is loose wiring, broken. 3) Check the output control signal cable is open circuit. Other matters: Please refer to the narrative part of mechanical vibration plate machine 7. Notes 1. The controller is strictly prohibited without customs of electricity allocated among the various contact socket; 2. Potentiometer is prohibited under the late unlocking adjustment potentiometer; 3. Abnormal failure can not be excluded, it shall promptly notify the professional staff carry out maintenance operations. Figure D 6 terminal wiring diagram 五. Instructions 1. Ensure that the vibration plate machine power input line is correct, the normal power supply, reliable, vibration plate fixed to the scaffold; 2.
