The comments (Kopinke, 2020) do not accurately represent the experimental conditions, parameter values, and conceptual model used in our study (Rusevova and Huling, 2020), leading to a misinterpretation of the results. The kinetic analysis used to determine the surface scavenging rate constant (k_S) involved competition kinetics between the probe and the mineral surfaces (Rusevova and Huling, 2020); similar competition kinetic methods have been used regarding other widely reported rate constants (Buxton et al., 1988; Dorfman and Adams, 1973). Assuming mass transport limitations prevented ·OH reaction at mineral surfaces, as proposed in the comments, estimates of k_S would be very small, or 0. However, the addition of solid phase media was found to effectively and consistently compete with the probe. The propensity of data, supporting data, and high degree of quality assurance and quality control measures provide multiple lines of evidence indicating a high level of certainty that ·OH scavenging occurred by solid surfaces.

评论（Kopinke，2020）不能准确地代表我们研究中使用的实验条件，参数值和概念模型（Rusevova和Huling，2020），从而导致对结果的误解。用于确定表面清除速率常数（k _S）的动力学分析涉及探针与矿物表面之间的竞争动力学（Rusevova和Huling，2020年）。关于其他广泛报道的速率常数，已经使用了类似的竞争动力学方法（Buxton等，1988； Dorfman和Adams，1973）。如评论中所建议，假设质量传输限制阻止了矿物表面的·OH反应，则k _S的估计值可能很小或为0。但是，发现添加固相介质可以有效且始终如一地与探针竞争。数据的倾向性，支持性数据以及高度的质量保证和质量控制措施提供了多条证据，表明对固体表面发生·OH清除的高度确定性。
