Statement of Retraction: Experimental study and numerical prediction of HTO and 36Cl− diffusion in radioactive waste at Téguline Clay

We, the Editor and Publisher of Environmental Technology, have retracted the following article:

Yun-yi Zhang, Yong He, Bing-bing Li & Ke-neng Zhang, Experimental study and numerical prediction of HTO and 36Cl− diffusion in radioactive waste at Téguline Clay, Environmental Technology, Latest Articles, 10.1080/09593330.2021.1939433

Following publication, errors have been identified in the experimental work and numerical simulation as follows:

• 1) The experimental results presented in this paper are too limited to effectively support the numerical analysis.

• 2) Although XRD, MIP, SEM and other microstructural tests were conducted and presented in this paper, the results of these microstructural tests have not been used in the numerical analysis, leading to incorrect results shown in Figure 11.

• 3) There is a serious discrepancy between the simulated results and the real conditions, due to an incorrect selection of diffusion parameters and initial concentration (200 mg/L and 500 mg/L) as well as an incorrect simulation model and boundary condition (Figure 4).

• 4) The simulation software (Geo-studio + MATLAB) appears to be unsuitable for the simulation work in this paper due to physical, mechanical and adsorption properties of the sample not being considered in the simulation.

These errors were identified and acknowledged by the authors. The errors are too substantial to be corrected in a corrigendum and will alter the conclusions of the paper. There are no concerns regarding research or publishing conduct, and the authors plan to revisit the relevant mature results of their research and may resubmit the revised paper for consideration by the journal.

We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.

撤回声明：Téguline Clay 放射性废物中 HTO 和 36Cl− 扩散的实验研究和数值预测

我们，环境技术的编辑和出版商，已经撤回了以下文章：

Yun-yi Zhang, Yong He, Bing-bing Li & Ke-neng Zhang, Téguline Clay 放射性废物中 HTO 和 36Cl− 扩散的实验研究和数值预测,环境技术, 最新文章, 10.1080/09593330.2021.1939433

发表后，在实验工作和数值模拟中发现了如下错误：

• 1）本文提出的实验结果太有限，无法有效地支持数值分析。

• 2) 虽然本文进行并介绍了 XRD、MIP、SEM 和其他微观结构测试，但这些微观结构测试的结果并未用于数值分析，导致结果不正确，如图 11 所示。

• 3）由于扩散参数和初始浓度（200 mg/L和500 mg/L）选择不正确，模拟模型和边界条件不正确（图4）。

• 4) 模拟软件（Geo-studio + MATLAB）似乎不适合本文的模拟工作，因为模拟中没有考虑样品的物理、机械和吸附特性。

作者发现并承认了这些错误。这些错误太大而无法在更正中更正，并且会改变论文的结论。没有关于研究或发表行为的担忧，作者计划重新审视他们研究的相关成熟成果，并可能重新提交修改后的论文供期刊考虑。

我们在决策过程中了解了我们的出版道德和诚信政策以及 COPE 关于撤稿的指南。

被撤回的文章将保持在线以维护学术记录，但将在每一页上以数字水印标记为“已撤回”。
