Prepared a electrode with high concentration and strong active oxidizing property which used titanium as anode’s substrate material, used gradient method the anode surface was coated with a definite ratio RuO2, TiO2, IrO2, SnO2, Ga and Ce in order to extend the operational life span.
Thus the life span of the positive plates is greatly lengthened that the principal causes include three: first, the titanium positive plate is very compact, even and few short fissures which can increase the binding force between coating and plate, increase the anti-scour ability from the electrolysis gas; second, few short fissures can decrease electrolyte permeating into surface coating, thus decrease the chemical and electrochemical solution of surface coating, lengthen the life span of active material; third, few short fissures can prevent and decrease the active oxide produced in the process of electrolysis permeating into titanium substrate, then produce poor conductor TiO2 resulting in the inactivation of titanium positive plate.
Chlorine precipitation potential Chlorine precipitation potential is an important factor reflecting the catalytic activity of electrode materials, during electrochemistry oxidation process external source outputs voltage, under the action of titanium positive plate chloride ion reacts to form high oxidant activity substances as ·OH, Cl2, OCl- which can improve the removal efficiency of ammonia nitrogen, total nitrogen and organics, the lower chlorine precipitation potential shows the higher catalytic activity which can generate of chlorine at positive plate, meanwhile inhibit other electrochemical reaction gassing process. 2 Experimental method: prepare NaCl saturated solution with deionized water, titanium positive plate is working electrode, stainless steel plate is auxiliary electrode, saturated calomel electrode is reference electrode, the positive plate area is 2cm2, according to references select the test conditions of electrochemical workstation, the chlorine precipitation potential
Tafel curve of titanium positive plate is shown in figure 2. 1 Fig.1 the secondary electrons picture of positive plate Fig. 2 the chlorine precipitation curve of titanium positive plate with Ti as substrate material The experimental result shows with the voltage increase from 0.2V to 0.8V the current changes not so obviously that shows in solution the electrochemical reaction rate is very slow, when the voltage increase to 0.945V(the horizontal ordinate data of intersection of curve 1 and curve 2), the current changes so obviously that shows in solution electrochemical reaction beginning to accelerate, comparison with the standard electrode potential of Cl- reacting to form ClO- 0.890V, the small differentials of over potential shows the low titanium positive plate potential of forming ClO- and the prior selection of chlorine, thus the high oxidant activity substances as ClO- can form under low potential which is beneficial to removing ammonia

When an N-type semiconductor material and a P-type semiconductor material connect into a galvanic pair, as DC in the circuit, energy will be transferred.
Endothermic and exothermic size is determined by the size of the DC as well as the number of parts of semiconductor materials N, P.
