[求助]
親們,江湖告急,求翻譯!有關(guān)高吸水性樹(shù)脂的合成與溶脹性能
|

| In addition, the repulsion between and among different chains is enhanced. The water absorbency increases as the force caused by chain expansion in the network increases (Pourjava & Amini-Fazl, 2007). However, when the neutralization degree is too high, the Na+ concentration on the network of graft copolymers being formed increases, and the electrostatic repulsion between charges causes the contact of the heavy metal and coordination groups on the surface of the resin and chelate formation difficult. The excess in the degree of neutralization is not conducive to resin adsorption. However, with the increase in the neutralization degree, the shielding effect of Na+ on the carboxylic acid anion in the system gradually appears, which weakens the repulsion among the chains or adjacent carboxylic acid anions on the same chain and reduces the extension driving force of the network. Therefore, when the neutralization degree is too high, the swelling capacity is reduced. |

此外,不同鏈間的相互排斥作用也增強(qiáng)了。其吸水率隨著網(wǎng)絡(luò)結(jié)構(gòu)中鏈膨脹作用力的增強(qiáng)而增加。但當(dāng)中和度過(guò)高時(shí),形成的接枝共聚物中,其網(wǎng)絡(luò)結(jié)構(gòu)中的鈉離子聚集濃度會(huì)增加,而且在兩電極間存在靜電排斥作用,這將減弱樹(shù)脂及螯合物表面上的重金屬(離子)與有機(jī)配體(或官能團(tuán))間的聯(lián)系(連接)。中和度的過(guò)量并不會(huì)引起樹(shù)脂吸附,但隨著中和度的增加,系統(tǒng)中鈉離子對(duì)羧酸陰離子的屏蔽作用會(huì)逐步顯現(xiàn),這會(huì)減弱不同有機(jī)鏈間或同一鏈內(nèi)相鄰羧酸陰離子間的排斥作用,還會(huì)減小網(wǎng)絡(luò)結(jié)構(gòu)擴(kuò)展的驅(qū)動(dòng)力。因此當(dāng)中和度過(guò)高時(shí),其膨脹量將減小。 |
