We investigated the simultaneous removal of phosphate and nitrite ions from aqueous solutions by acombination treatment that used both PG-Ca (poly-g-glutamic acid combined with flocculating agents)and SB600 (soybeans treated with calcium chloride, hydrochloric acid and calcined at 600 8C). Phosphateions and nitrite ions were selectivity adsorbed by PG-Ca and SB600, respectively. The removalmechanism of phosphate ions from aqueous solution was related to the presence of calcium hydroxide(derived from PG-Ca), and that of nitrite ions was related to the presence of chloride ions at the surface ofSB600.

Nickel hydroxide (Ni) was calcined at 270 and 400 8C (denoted Ni270 and Ni400), and the properties ofNi, Ni270, and Ni400 were investigated. In addition, the phosphate adsorption capabilities of Ni, Ni270,and Ni400 were evaluated by examination of the effects of contact time and solution pH, analysis of anadsorption isotherm, and study of desorption. The amounts of phosphate ion adsorbed by the differentsamples showed the order Ni < Ni400 < Ni270. Finally, phosphate ions adsorbed onto Ni270 could bedesorbed using sodium hydroxide, indicating that Ni270 can be used as a renewable adsorbent.
Development of a New Tooth Profile Designed for High Efficiency P/M Internal Gear Pump Rotors

We developed a new tooth profile designed for P/M internal gear pump rotors. The theoretical discharge volume of the new tooth profile internal gear rotors is more than 10% higher than that of the same size conventional rotors. Our new profile rotors can achieve a decrease in torque, and fuel-efficiency will also be improved.
