Abstract

The development of low-cost animal bedding materials for ammonia (NH3) mitigation in livestock facilities is highly desirable from both environmental and waste management perspectives. In this study, we developed an air oxidation method as a simple but effective approach to increase the NH3 adsorption capacity of relatively ubiquitous bituminous coal (BC). The BC samples were oxidized in air at a range of temperatures, from 100 to 550 °C, and the highest NH3 adsorption was observed from the BC modified at 300 °C, with an 11-fold increase (49.7 mg g−1) compared with the initial BC. Samples were characterized using microscopy, BET, FT-IR, XPS, and Boehm titration. The results indicated that NH..
