Environment, Health & Safety Hazardous
2 3 Introduction The safe storage of hazardous chemicals is an essential part of an environmental, health, and safety program. Chemical storage facilities must meet certain minimum standards to satisfy diverse regulations, such as those of
Aluminium chloride (AlCl 3), also known as aluminium trichloride, describe compounds with the formula AlCl 3 (H 2 O) n (n = 0 or 6). They consist of aluminium and chlorine atoms in a 1:3 ratio, and one form also contains six waters of
Aluminium sulfate
Aluminium sulfate is a chemical compound with the formula Al 2 (SO 4) 3.It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and wastewater

Polyethylene terephthalate
Polyethylene terephthalate (sometimes written poly (ethylene terephthalate) ), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family and is used in fibres for
Prior to the early 1970s, most trichloroethylene was produced in a two-step process from acetylene. First, acetylene was treated with chlorine using a ferric chloride catalyst at 90 °C to produce 1,1,2,2-tetrachloroethane according to the
- What is poly aluminum-ferric chloride (PAFC)?
- Author to whom correspondence should be addressed. Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 °C for 1 h and 3% CaF 2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 °C for 4 h.
- Is polyaluminum ferric chloride an inorganic coagulant?
- 1. Introduction Polyaluminum ferric chloride (PAFC) is an efficient inorganic polymeric coagulant [1], [2]. Many studies [3], [4], [5] have demonstrated that inorganic polymeric coagulants were more effective than conventional inorganic coagulating salts in coagulation due to their resistances to the influence of wastewater initial pH.
- How is PAFC prepared?
- PAFC is prepared by microwave synthesis with a shortened time of 5 min and the conditions of preparation are optimized. Its performance is better than that of the commonly used polymeric aluminum chloride (PAC) and polymeric iron chloride (PAF).
- How is PAFC synthesized?
- PAFC was synthesized following two steps: First, 50 g of blast furnace dust was placed in a 500 mL three-necked round bottom flask equipped with stirrer and reflux device. Then, 2 g NaF, 150 mL of HCl diluted solution (36%, freshly diluted 1:1 with ultrapure water) and 5 mL of HNO 3 were added.
