Due to their toxicity, Cd(II) and Ni(II) ions in the environment are severe. The hydroxyapatite composite was improved with magnetic MnFe2O4 to remove Cd(II) and Ni(II) ions from an aqueous solution. Hydroxyapatite was extracted from Snakehead (Channa str... see more

The clean water treatment process changes the physical, chemical, and biological properties of water so that it meets the requirements for use as drinking water or daily needs. The purpose of this research is to analyze the performance of ceramic membrane... see more

Cr(III) is one of the most stable chromium species in nature, Cr(III) species are not carcinogenic to humans, but if the levels in the body exceed 0.2 mg / day it is very dangerous for the body especially in the respiratory tract. The presence of chromium... see more

Eggshell is a solid waste that is available in abundance but is being left unused. Eggshell containing calcium in a high amount. Calcium can be used as a precursor for hydroxyapatite (HAp). Modification of HAp with SiO2 is expected to improve its low mech... see more

The NiFe2O4 nanoparticle was synthesized using co-precipitation method. This study done to the purpose for get the photocatalyst magnetic. The product of NiFe2O4 nanoparticles were characterized by XRD, FTIR, SEM EDS and UV DRS instrumentation. The result... see more

The effect of initial Congo Red and Procion Red concentration on isotherm adsorption and thermodynamic adsorption study using natural and Zn/Fe Pillared bentonite have been conducted. The adsorbents were also characterized by Fourier transform infrared (F... see more
