Product specification

Product application

1.Polyferric sulfate 19% is mainly used for water purification treatment, and has

remarkable effects on removing turbidity, decolorization, deoiling, dehydration,

bacteria, deodorization, algae, COD, BOD and heavy metal ions in water, etc.

2.Polyferric sulfate 19% is widely used in industrial wastewater treatment, such as

printing and dyeing wastewater, as well as in casting, papermaking, medicine and

leather making.

FeSO₄·7H₂O is a commonly used chemical raw material, which is widely applied in

various fields such as electronics and electrical appliances, automobile parts, mechanical

equipment, household products, pesticides, and pharmaceuticals. In industry, it is a raw
material for the preparation of various iron salts, iron-based pigments, polymeric ferric
sulfate, ink and other products.

Polyferric silicate sulfate (PFSS) is a new type of inorganic polymer flocculant, which is

widely used in the purification processes of industrial sewage from alcohol, chemical,

electroplating, ore dressing, printing and dyeing, pharmaceutical,coking and other

industries as well as domestic drinking water. Hematite slag, as a solid waste in the

production process, contains some valuable metal ions as well as heavy metal ions.

Random burying or piling up will not only pollute the environment but also waste

resources.

The comprehensive utilization of hematite slag can turn waste into treasure, increase

the utilization rate of enterprise products and reduce costs, achieving the exploration

goals of environmental benefits, social benefits and economic benefits.In this project,

hematite slag was first used as a raw material to prepare FeSO₄·7H₂O, and then

FeSO₄·7H₂O was used as a raw material to prepare PFSS. The process conditions

of the two products were explored respectively by combining single-factor experiments

and response surface experiments, and then the optimal conditions were obtained.

The products prepared under these conditions were characterized by means of ICP-AES,

XRD, TG-DSC, SEM, FTIR and other methods. The specific work is as follows:

(1) In the process of preparing ferrous sulfate heptahydrate from hematite slag as a raw

material, the combined method of single-factor and response surface experiments was

adopted to discuss the effects of leaching temperature, Polyferric Sulfate 19% concentration,

leaching time, liquid-solid ratio and stirring speed on the iron leaching rate in the acid

leaching experiment respectively, as well as the effects of reduction reaction temperature,

reaction time and excess coefficient of iron powder on the reduction rate.

Our Factory

The optimal conditions for the acid leaching experiment were obtained as follows: the

leaching temperature was 106 °C, the sulfuric acid concentration was 47%, the leaching

time was 2.65 h, the liquid-solid ratio was 4:1, and the stirring speed was 300 r/min.

The optimal conditions for the reduction experiment were obtained as follows: the

reaction temperature was 80 °C, the reaction time was 2 h, and the excess coefficient

of iron powder was 1.2.

(2) During the crystallization process of the Polyferric Sulfate 19% solution, ethanol

was added to the solution at a ratio of Vethanol:VH₂O = 1:1 to conduct a recrystallization

reaction.The finally obtained FeSO₄·7H₂O was characterized by ICP-AES, XRD,

TG-DSC and SEM. The results showed that the FeSO₄·7H₂O product met the requirements

of the analytical pure grade of chemical reagent ferrous sulfate heptahydrate specified in

GB/T 664-2011.

(3) In the process of preparing PFSS from FeSO₄·7H₂O as a raw material by the blending

oxidation method, the combined method of single-factor and response surface experiments

was adopted to discuss the optimal conditions for the preparation of PFS and PS

respectively. In the experiment of synthesizing PFS, the results of three indicators, namely

the total iron content, density and basicity of PFS, were measured by chemical analysis

methods. The optimal conditions for synthesizing PFS were obtained as follows: the addition

amount of concentrated sulfuric acid was 4.70 g, the reaction temperature was 30 °C, the

aging temperature was 20 °C, and the aging time was 9 h.Under the optimal conditions,

the basicity of the prepared PFS reached 14.21%, with high stability, meeting the

requirements of the first-class product of water treatment agent - polymeric ferric sulfate

specified in GB/T 14591-2016.

(4) The factors affecting

the stability of PS were explored by combining single-factor experiments and response

surface experiments, and the optimal conditions were obtained as follows: the SiO₂

content was 3%, the activation temperature was 30 °C, and the pH value after activation

was 3. (5) PFS and PS were subjected to a blending reaction. Through single-factor

experiments with turbidity as an indicator, the optimal conditions were obtained as

follows: the Fe/Si ratio was 1, the aging time was 2 h, and the activation time was 30 min.

The PFSS prepared under the optimal conditions was characterized and analyzed by

XRD, FTIR and SEM, and compared with the corresponding characterizations of PFS.

The results showed that the product PFSS is a new type of high-molecular polymer.
