Shuitu Baochi Xuebao, 2017 为确定添加生物质炭对旱作农田土壤持水特性的影响，在隆中黄土高原典型旱作农田区设置相关定位试验，对不同生物质炭输入水平的土壤容重、土壤孔隙度、土壤水分常数及土壤水分特征曲线进行测定。结果表明，生物质炭的添加能够减小土壤容重，增加土壤孔隙度。随着生物质炭输入水平的增加，土壤容重的减小及土壤孔隙度的增加幅度加大。生物质炭达到50 t/hm2时土壤结构变化最为明显，0—5，5—10，10—30 cm土层中土壤容重相比对照分别减小7.01%，9.91%，16.60%，土壤毛管孔隙度分别增加19.47%，21.02%

Shuitu Baochi Xuebao, 2019 以法国梧桐叶片和枝条为原料在500℃下通过限氧裂解法制成生物质炭，进而采用批量吸附法探究了不同溶液初始pH、吸附时间、溶液初始Pb2+浓度对生物质炭吸附效果的影响，并通过拟合吸附动力学曲线和吸附等温线方法初步研究吸附机理。结果表明，与法国梧桐枝条炭相比，叶片炭矿质元素组成相对较为复杂，官能团种类较丰富。2种生物质炭均在吸附时间为24 h时、初始pH为5时达到最大吸附量，叶片炭的最大吸附量比法国梧桐枝条炭高25.6%。2种生物质炭的动力学吸附过程均符合准二级动力学方程，表明吸附速率主要受化学因素控制 ...

Shuitu Baochi Xuebao, 2021 为了明确活性炭工业的副产品——杏壳生物炭和水分管理模式对石灰性土壤重金属有效性的钝化效果，采用重度Cd、As复合污染的农田土壤，通过土壤培养方法探索了干湿交替水分管理模式下，添加不同用量生物炭对土壤中Cd、As有效性的影响。结果表明：从土壤溶液中Cd、As浓度的变化来看，干湿交替培养条件下，添加2%~10%生物炭处理的土壤溶液中Cd浓度均显著低于对照（P < 0.05），降幅为33.1%~62.2%，说明干湿交替模式下添加生物炭显著促进了Cd由土壤液相向土壤固相的转移 ...
