Chapter 10, ‘Technical Implications of Organic Synthesis in Ball Mills’ by Achim Stolle explains that ball mills are characterised by different parameters, regardless of the type of process. This information is of value not just for organic synthesis but for general applications.
The dry milling was carried out at 300 rpm with a ball-to-powder weight ratio of 10:1. The as-milled pure and composite samples were annealed at 450 °C for 1 h in an alumina crucible to remove lattice strain in the sample obtained during ball mill process.
Brominated organic pollutants are considered of great concern for their adverse effect on human health and the environment, so an increasing number of such compounds are being classified as persistent organic pollutants (POPs).

Cheng Ding is a professor and an adjunct professor at the Yancheng Institute of Technology and Jiangsu University, respectively. He earned his Ph.D. in Environmental Engineering from Southeast University in China. Prof. Ding’s reasearch is mainly on wastewater treatment, ecological process of organic pollutants, and pollution control technology.
The photo-Fenton process was reported as more efficient than Fenton treat-ment. In some cases, use of sunlight instead of UV irradiation reduced the costs . However, this offers a lower degradation rate of pollutants. Acidic condi-tions (about pH 3) were also reported to be favorable and this may be mainly
