Natural Rubber Sheet Production Wastewater Properties and Treatability by Zero-Valent Iron-Modified Agricultural Residual Biochar for Sustainable Treatment
The production of one ton of natural rubber sheets generates 10–18 m3 of natural rubber sheet production wastewater (NRW), containing diammonium phosphate, tetramethylthiuram disulfide/zinc oxide (TMTD/ZnO), and formic acid. This study evaluated palm shell biochar (PSB), Longkong wood biochar (LWB), and their zero-vale...
