- Note that the magnitude of the pasteurization process does depend on the pH of the product; high pH products require somewhat more severe thermal processes. 注意,巴氏杀菌过程的强度取决于产品的ph值,高ph值产品需要较强的热处理。
- A high pH level characterizes commercial bleach, which consists of a nominal 15% solution of sodium hypochlorite along with approximately 1- 2% of sodium hydroxide to act as a chemical stabilizer. 当球阀在不工作期间关闭，经过一段时间，漂白剂将分解并释放出氧气。
- The results indicate sodium formate and sodium aceta te present low pH when neutralization, sodium bicarbonate and ammonium carbonate present high pH,and the Bayer PAK has better properties. 结果表明甲酸钠和乙酸钠为低pH中和剂,碳酸氢钠和碳酸氢铵为高pH中和剂,Bayer公司的PAK综合性能较好。
- The results show that octanol content, pH and ionic strength are key factors. Under the con ditions of low ionic strength(C_kcl=0.05 mol/L),high pH value(pH>13.6 6)and octanol content 0.85%(volume fraction),the extraction efficiency approac hes 100%. 结果表明 ;正辛醇的量、水相 pH值是萃取过程的关键因素 ;在低离子强度 (CKCl=0 .;0 5mol/L)、高 pH值(pH =13 6 6 )、含正辛醇体积分数为 0 85%25的情况下;萃取率接近 10 0%25
- The property of CaCO3 inhibition of PESA was investigated by static tests whichrevealed that PESA has high scale inhibition performance, and is suitable for high pH value and hard water. 采用静态阻垢法考察了PESA阻碳酸钙垢的性能，结果表明，PESA具有良好的阻垢性能，适用于高碱高固水系。
- Meanwhile, the porous flocs structure with lower fractal dimension form at acid conditions than those forming under higher pH condition. 在中性条件下，无明显丝状菌生长，絮体平均粒径减小，分形维数较高，结构致密；
- Recirculation could improve leachate quality dramatically with lower TOC, COD, BOD, VFA, NH+4-N, SS and higher pH level which made leachate treatment easy. 回灌能明显改善渗滤液水质;显著降低总有机碳(TOC)、化学需氧量(COD)、生化需氧量(BOD)、挥发性脂肪酸(VFA)、氨氮(NH4+-N)和悬浮固体(SS)浓度;并提高pH值;降低渗滤液处理难度.
