Abstract

This article focuses on implementing multivariate analysis to evaluate biochar-derived carbonaceous nanomaterials(BCN) from three different feedstocks for the detection and differentiation of heavy metal ions inaqueous systems. The BCN were produced from dairy manure, rice straw and sorghum straw bi...
