For the system NaNO3–NaCl–NaNO2, the calculated and experimental temperatures differ are very small below 673 K, but the oxidation and decomposition of the mixed salts are found when the temperature is higher than 673 K. Meanwhile, the eutectic point is obtained from calculated phase diagram ...
Pollution caused by Cr(VI) metal is harmful because it is toxic and carcinogenic. Utilization of cow bone waste is considered not optimal. One of the utilization is as an adsorbent of Cr(VI) metal. This research aims to determine the adsorption capacity by bone waste bone adsorbent in lowere...
