摘要

选取5种原料制备的生物炭胶体在磺胺二甲基嘧啶(SMT)存在条件下进行柱迁移实验,并利用二维相关-傅里叶变换红外光谱(2D-COS-FTIR)以及线性回归,主成分分析(PCA)和随机森林模型分析等方法探究SMT对生物炭胶体迁移的影响机制.结果表明:SMT在5种生物炭上的吸附量差异较大(1.86 ~ 4.52mg/g),这与生物炭的碳氢含量呈显著的线性相关关系(R²> 0.70).SMT导致5种生物炭胶体的zeta(ζ)电势显著正移,其与石英砂之间的最大排斥势垒(F_max)显著降低,导致其迁移率(M_eff)显著降低.线性回归分析显示M_eff与ζ电势呈显著的线性相关关系(R² = 0.88),并且PCA和随机森林模型分析均证明ζ电势是影响M_eff的最直接因素.两点动力学模型拟合结果显示,R²均大于0.97,SMT存在条件下5种生物炭胶体的可逆位点附着系数(k_att)和最大固相浓度(S_max)值均增加.生物炭的原材料种类和SMT吸附共同调控其胶体迁移能力.

Abstract

This study investigated the effects of SMT on biochar colloid transport using column experiments with five biochars produced from contrasting feedstocks, combined with spectroscopic (2D-COS-FTIR) and statistical analyses (linear regression, principal component analysis and random forest analysis) to identify the dominant controlling mechanisms. The results showed SMT adsorption capacity varied widely among the five biochars (1.86~4.52mg/g), and showed strong linear relationships with their carbon and hydrogen contents (R² > 0.70), highlighting the importance of feedstock-dependent physicochemical properties. The presence of SMT consistently shifted the zeta (ζ) potential of biochar colloids toward more positive values and markedly reduced the electrostatic energy barrier (F_max) between biochar colloid and quartz sand. This change substantially decreased colloid mobility (M_eff), indicating enhanced retention within the porous medium. Linear regression analysis showed that M_eff was closely related to the ζ potential (R²= 0.88). In contrast, both PCA and random forest model analyses confirmed ζ potential as the most critical factor affecting M_eff. Furthermore, the fitting results from the two-site kinetic model (R²>0.97) showed that both the reversible site adhesion coefficient (k_att) and maximum solid concentration (S_max) increased for all five biochar colloids in the presence of SMT. These findings demonstrate that biochar feedstock types and SMT adsorption jointly influence the mobility of biochar colloid.
