摘要
对新近发明的“实用型氧气发生剂”进行了动力学研究,并提出了其氧气发生的可能机理:在有水存在下,一定配比的OG粉末(CaO2>70%)与TG粉末(FePO4·nH2O)所构成的反应物/产物体系,消除了Ca(OH)2对水扩散的阻滞作用,以及新产生的微小Fe(OH)3晶体对氧脱附的催化作用。该氧气发生剂在有水(淡、海水)存在的条件下,能够连续、稳定、均衡、在较长时间里向水生生物供应代谢所需的溶解氧,具有用水量少,用剂量省、单位剂量发氧量高,有效氧利用率高的特点,具有使用的经济性和实用性。
A new type of O 2 generating agent, called the Applicable type of O 2 generating Agent,or briefly AOGA,had been invented by us Its O 2 generating Kinetics is studied The results of the kinetic experiments are reported The applicable mechanism are summairzed as follows:in water (fresh or marine) the AOGA forms a system of materials which has a certain degree of diffusion to H 2O,thus decreasing Ca(OH) 2 resistance to the diffusion of water into AOGA,and the new Fe(OH) 3 ting crystals may catalyze the adsorption of O 2 on the surfaces of Fe(OH) 3
