[求助]
一段翻译，很头疼，困扰好几天了。请大神帮帮忙。

| 原文：此外，A和B两个吸附体系溶液中Cu2+含量随pH的变化关系（图4）也间接验证了ADS对Cr(III)和Cr(VI)吸附是两种不同的吸附机制。A体系由于氧化还原反应的发生产生了Cr(III)（图5），而B体系是以离子交换为吸附机理的，吸附后溶液中剩余的依然是Cr(III)（图６）。在较低pH时，A和B两个体系由于大量质子的存在，使吸附剂相对稳定，因此吸附后残液中Cu2+含量相对较低。随着pH增大，A和B两个体系产生的Cr(III)会对吸附剂中Cu-S键产生一定的破坏作用，故而吸附后溶液中Cu2+含量略有增加（图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. |
