Developing a novel packed in-tube solid-phase extraction method for determination
A novel plate-like nano-sorbent based on coppercobaltchromium layered double hydroxide was synthesized by a simple coprecipitation method. The synthesized nanoparticels were introduced into a stainless steel cartridge using a dry packing method. Then, the packed cartridge was introduced as a novel on-line packed in-tube configuration and followed by high performance liquid chromatography for the determination of trace amounts of
