Preparation of High Purity Mullite Ceramics

Preparation and coagulation efficiency of polyaluminium ferric silicate chloride composite coagulant from wastewater of high-purity graphite production.

The aim of the present work was to produce a polyaluminium ferric silicate chloride (PAFSiC) coagulant from acidic and alkaline wastewater of purifying graphite by roasting, and subsequently to evaluate coagulation efficiency of the reagent by treating surface water from the Yellow River as well as municipal wastewater in comparison with the conventional coagulant polyaluminium chloride (PAC). ...

Preparation of Iron Solution and Pancreatic Extract

Female rats of the Wister strain weighing approximately 250 g. were used in all experiments. They were fed on a commercial diet (supplied by D.H.A.-Rural). After an overnight fast the animals were given intraperitoneal nembutal (2 mg./100 g. of body weight) followed by ether anaesthesia. The abdomen was opened and a polythene tube was inserted into the proximal end of the jejunum. At a distance...
