[求助]
一段翻譯，很頭疼，困擾好幾天了。請大神幫幫忙。

| 原文：此外，A和B兩個吸附體系溶液中Cu2+含量隨pH的變化關(guān)系（圖4）也間接驗(yàn)證了ADS對Cr(III)和Cr(VI)吸附是兩種不同的吸附機(jī)制。A體系由于氧化還原反應(yīng)的發(fā)生產(chǎn)生了Cr(III)（圖5），而B體系是以離子交換為吸附機(jī)理的，吸附后溶液中剩余的依然是Cr(III)（圖６）。在較低pH時，A和B兩個體系由于大量質(zhì)子的存在，使吸附劑相對穩(wěn)定，因此吸附后殘液中Cu2+含量相對較低。隨著pH增大，A和B兩個體系產(chǎn)生的Cr(III)會對吸附劑中Cu-S鍵產(chǎn)生一定的破壞作用，故而吸附后溶液中Cu2+含量略有增加（圖７）。 |

The system A generated Cr(III) due to a redox reaction, while ion exchange was the mechanism for the system B, and Cr(III) was still the leftover after absorption (Figure 6). At relatively low pH, both absorbents were relatively stable, due to the presence of a large excess of protons, therefore the Cu2+ content in the processed liquids were relatively low. As the pH is increased, the Cr(III) produced in both systems deteriorated the Cu-S bonds in the absorbents, therefore after absorption the liquid had a slightly elevated Cu2+ content. |

In addition, the pH-dependent changes of Cu2+ contents in two absorption systems also indirectly verified that the mechanisms for absorption by ADS for Cr(III) and Cr(IV) is different. The system A generated Cr(III) due to a redox reaction, while ion exchange was the mechanism for the system B, and Cr(III) was still the leftover after absorption (Figure 6). At relatively low pHs, both absorbents were relatively stable, due to the presence of a large excess of protons, therefore the Cu2+ content in the processed liquids were relatively low. As the pH was increased, the Cr(III) produced in both systems deteriorated the Cu-S bonds in the absorbents, therefore after absorption the liquid had a slightly elevated Cu2+ content. |
