A novel metal sulfide: potassium niobium sulfide (KNbS) was prepared by hydrothermal method. The morphology and composition of KNbS were characterized by scanning electron microscopy and X-ray diffraction. It was confirmed that the adsorption process of KNbS was carried out by exchange reaction of K+ with Co2+ and Sr2+. The effects of pH, contact time, coexisting ions and initial concentration of...
Zeolit/Ag+ composite particles material (ZACPM) had been prepared using zeolite as carrier by carrying Ag+, solidifying Ag+ stably in the holes of zeolite and enhancing the adsorption property of zeolite. The effects of technological parameters on preparation of ZACPM, the air purification properties such as antibacterial property and the function of eliminating harmful gases and the microstructure...
