Preparation of high pure refractory grade magnesium oxide from east coast sea water

The Precipitation of Calcium and Magnesium from Sea Water.*

ApPARENTLYcalcium carbonate is precipitated in certain parts of the ocean by processes which are inorganic in so far as that the calcium does not first form a true constituent of organisms (Clarke, 1920, p. 128). The conditions governing solubility of calcium in sea-water have been reviewed by Johnston and Williamson (1916) with the conclusion that surface layers of the ocean are approximately ...

Preparation of High-Purity Grade Ammonium Sulfate from Locally Available Products

Five Sarsiellidae ostracods (Crustacea: Myodocopida) from the South Coast of Korea (East China Sea).

The East China Sea is part of the Warm Temperate Northwest Pacific zoogeographic province and, as such, has a high biodiversity and many tropical and subtropical biotic elements. Nevertheless, many invertebrate groups from this area remain poorly studied. Ostracods are one of them, especially those belonging to the subclass Myodocopa. In this paper we provide the first data on a diverse myodoco...

The Combined Effect of Copper Oxide and Magnesium Oxide Nanoparticles Against Water and Food Borne Bacteria

Background: The incidence of foodborne infectious diseases has been stable and even increased in many countries. Improper use of antibiotics due to the prevalence of microbial diseases has caused drug resistance. So nanotechnology has many attractive applications in the food industry, such as food preservation and food quality control. By the reason, the absorptive and antibacterial features of...

Preparation of Ceramic Composite Filter with Titanium Oxide Nanoparticles and Active Carbon Content for Treatment of Sea Water

In this mentioned study for sea water treatment ceramic composites were made from natural alumina and adsorbent active ingredients. According to the experimental results, filters along with active agents have acceptable effects on drinking water parameters and contaminants in compare with 1053 ISIRI standard. Modular set up was made for sea water treatment tests. Water flowrate after filtration...
