The method and principle of sodium silicate solution removal natrium silicate

For various kinds of pollutants, we can take on various methods of elimination methods. Here are a number of typical approaches and concepts of sodium silicate solution.

Precipitation method

The precipitation method is an approach that makes use of impurities ions to respond with certain chemical reagents to produce hard precipitation so as to remove it from the sodium silicate solution. For example, for metal ions such as iron ions and aluminum ions, alkaline reagents such as sodium hydroxide or potassium hydroxide can be contributed to develop it. The response formula is as complies with:

Fe ⁻ + 3oh f → Fe (OH) ↓

Al ⁻ + 3oh a → Al (oh) ↓

For calcium and magnesium ions, carbonate reagents such as salt carbonate or potassium carbonate can be included in create carbonate rainfall. The reaction equation is as adheres to:

CA ₃ ² ⁻ + Carbon monoxide c → CACO ₃ ↓

Mg ₃ ² ⁻ + Carbon monoxide m → mgco ₃ ↓

The rainfall approach is easy and the expense is low, yet you require to take notice of the quantity and response conditions of the debris to guarantee that the contaminations ions can be totally precipitated.

More than a hundred schools in the UK have been closed due to the risk of collapse

In the UK, more than 100 schools were closed because of the danger of collapse

In the UK, many schools use Autoclaved aerated cement (RAAC). This is a concrete material that is lighter.

In 2018, the roof collapsed of a primary-school in southeast England. Later, it was discovered that RAAC material had been used to build the school's roof and other buildings. This raised safety concerns.

BBC reported that RAAC materials were widely used from the 1950s until the mid-1990s in areas such as roof panels, and had a lifespan of around 30 years.

According to reports, the risk of building collapse is not only present in schools, but also in hospitals, police station, and other public structures. RAAC material has been found.

The Royal Dengate Theatre at Northampton is temporarily closed after RAAC material was found.

According to NHS, RAAC has been detected in 27 hospital building.

The NHS chief has been asked for measures to be taken to prevent collapse.

BBC reported that since 2018 the British government has warned schools to be "fully ready" in case RAAC is found within public buildings.

The Independent reported Jonathan Slater a former senior education official, who said Prime Minister Sunak, when he was chancellor of treasury in 2021, approved budget reductions to build schools.

Nick Gibb is a senior official at the Department of Education. He said that the Department of Education asked for PS200m annually for school maintenance. Sunak, then the chancellor, only provided PS50 million per year.

The report also states that despite Sunak having promised to renovate at least 50 schools every year, in the main reconstruction plan of the government only four schools were renovated.

The British National Audit Office chief also criticised this crisis. He claimed that the Sunak government had adopted a "plaster-method" of building maintenance.

He believes the government's underinvestment has forced schools to close, and that families are now "paying the cost".

Paul Whitman is the secretary-general of National Association of Principals. He said parents and public will see any attempt of government to shift blame to individual schools, as a "desperate attempt to divert attention away from its own serious mistakes."

Whitman claimed that the classroom has become completely unusable. Whitman blamed the British Government for the situation. "No matter what you do to divert or distract, it won't work."

London Mayor Sadiq khan said that the government should be transparent. This will reassure parents, staff, children, and others.

BBC reported schools in the UK were pushing forward with inspections and assessments. Children who had been suspended because of school building issues will be temporarily housed, or they can learn online.
