Compare with control group, concentrations of hemoglobin in ferrous sulphate groups supplemented with 40 and 80mg/k cysteamine were increased 10.34% and 19.44% respectively, and 13.42% and 31.16% were increased respectively in those of methionine chelated iron grouops.
Abnormal behaviour was not found when Colossoma brachypomura were immersed in the solution of methylene blue of 2.1 ppm concentration and the mixture of copper sulphate and ferrous sulphate (ratio 5: 2)of 5.6 ppm concentration respectively for 240 hours.
Calcium hydroxide,aluminium sulphate,calcium nitrate and ferrous sulphate have been applied to treating wastewater of phosphorus for 24 days in manner of 1∶1,1∶2 and excessive. The results show that max reduction ratios of phosphorus are 86.2%,91.7%,90.3% and 93.1%,respectively,but the effect of treatment fluctuates in the test period.
Through technical approach to application of iron fertilizer, the results showed that spraying 2500 ppm ferrous sulphate solution 2 or 3 times in flowering period was suitable with increasing yield 17.5%and 22.9% respectively.
The research result shows that the optimum pH values of alum,ferric chloride and ferrous sulphate are respectively 8.5, 8.5 and 9. At their optimal pH values,the optimial volums of these coagulants are 200mg/l,250mg/l and 400mg/l respectively.
The results showed that the ferrous sulphate,urea and humic acid mixture(0.1%FeSO_4+0.2%HA+0.5%Urea) could significantly increase iron content in green pea seeds,but adversely affect zinc accumulation.
When phosphate and ferrous sulphate were used as stabilizers to treat heavy metals in APC-residues,the CO 2 pretreatment influenced the stabilization effect of Pb and Cd negligibly,but faˉcilitated to control the release of Cr in the leaching test.
Experimental results showed that the effective diffusion coefficient of ferrous sulphate decreased with the increase of alginate concentration,the optimum alginate concentration is 2%(W/V).
The increase in haemoglobin was significantly higher with ferrous sulphate than with whole wheat (p>amp;lt;0.05), spirulina and whole egg (p>amp;lt;0.01).
The present study was carried out to investigate the availability of iron from spirulina, whole wheat, whole egg and standard ferrous sulphate in terms of haemoglobin formation, serum and tissue iron levels.
Since the usefulness of o-carboxymetbylmercaptobenzenestibonic acid(Ⅱ)against trypanosomiasis,trichomoniasis and leisbmaniasis was announced,its m-(Ⅲ)and p-isomem(Ⅳa)have been prepared in our laboratory.The lattercompound(Ⅳa)was found to be more active than tartar emetic against schis-tosomiasis japonica in a long course treatment in mice.In order to examinethe relationship between the chemical structure and the pharmacological activity,the corresponding ester(Ⅳb),amide(Ⅳc),alcohol(Ⅳd)and sulphone(Ⅳe)were t...
This paper describes the growth condition of PeOOH in the solution of ferrous sulphate with NaOH or NH4OH as precipitant. The crystal forms were observed with electron microscope. The phase composition and phase boundaries were determined by X-ray diffraction. When the precipitant is NH4OH or NaOH, the two phase diagrams of the FeOOH growth in the acid region are similar, but in the alkaline region they are different.
A study has been made on the flotation of the wolframite slimes taken from the Yao Gang Xian Mine, Hunan Province of China. The flotation reagents used consist of O. P. toluene arsonic acid or benzyl arsinic acid (collector), Medialan (auxiliary collector), ferrous sulphate (activator), sodium humate (a salt of humic acid) and sodium silicate (depressant) and their flotation conditions are given. These reagents have better selectivity and collecting action and may promote the activation and depr...
